Calculating Traffic Fatalities: Male Probability Analysis

To solve the problem, we will calculate the probabilities step by step.

Part 1: Determine ( P(\text{male}) )

To find ( P(\text{male}) ), we use the formula:

[ P(\text{male}) = \frac{\text{Number of males}}{\text{Total number of individuals}} ]

From the data provided:

  • Number of males = 18,056
  • Total number of individuals = 57,443

Now we can calculate ( P(\text{male}) ):

[ P(\text{male}) = \frac{18,056}{57,443} \approx 0.314 ]

Part 2: Determine ( P(\text{male} | \text{passenger}) )

To find ( P(\text{male} | \text{passenger}) ), we use the formula:

[ P(\text{male} | \text{passenger}) = \frac{\text{Number of male passengers}}{\text{Total number of passengers}} ]

From the data provided:

  • Number of male passengers = 11,713
  • Total number of passengers = 44,619

Now we can calculate ( P(\text{male} | \text{passenger}) ):

[ P(\text{male} | \text{passenger}) = \frac{11,713}{44,619} \approx 0.262 ]

Part 3: Are the events "male" and "passenger" independent?

To determine if the events "male" and "passenger" are independent, we check if:

[ P(\text{male} | \text{passenger}) = P(\text{male}) ]

From our calculations:

  • ( P(\text{male}) \approx 0.314 )
  • ( P(\text{male} | \text{passenger}) \approx 0.262 )

Since ( P(\text{male} | \text{passenger}) \neq P(\text{male}) ), the events are not independent.

Conclusion

  • Part 1: ( P(\text{male}) \approx 0.314 )
  • Part 2: ( P(\text{male} | \text{passenger}) \approx 0.262 )
  • Part 3: The answer is D. No. The occurrence of the event "passenger" affects the probability of the event "male."

University Survey Results on Student Government Satisfaction

To solve the problems, we first need to calculate the total number of students in each category and then use that information to find the probabilities.

Given Data:

  • Freshman:
    • Satisfied: 52
    • Neutral: 26
    • Not satisfied: 21
  • Sophomore:
    • Satisfied: 52
    • Neutral: 20
    • Not satisfied: 22
  • Junior:
    • Satisfied: 60
    • Neutral: 20
    • Not satisfied: 11
  • Senior:
    • Satisfied: 57
    • Neutral: 10
    • Not satisfied: 28

Total Students:

To find the total number of students surveyed, we sum all the students in each category:

[ \text{Total} = (52 + 26 + 21) + (52 + 20 + 22) + (60 + 20 + 11) + (57 + 10 + 28) ]

Calculating each class:

  • Freshman: (52 + 26 + 21 = 99)
  • Sophomore: (52 + 20 + 22 = 94)
  • Junior: (60 + 20 + 11 = 91)
  • Senior: (57 + 10 + 28 = 95)

Now summing these totals:

[ \text{Total} = 99 + 94 + 91 + 95 = 379 ]

Part (a): Probability that a participant is satisfied

To find the probability that a randomly selected participant is satisfied, we sum the number of satisfied students:

[ \text{Satisfied} = 52 + 52 + 60 + 57 = 221 ]

Now, we calculate the probability:

[ P(\text{satisfied}) = \frac{\text{Number of satisfied students}}{\text{Total number of students}} = \frac{221}{379} ]

Calculating this gives:

[ P(\text{satisfied}) \approx 0.583 ]

Rounded to three decimal places:

[ P(\text{satisfied}) \approx 0.583 ]

Part (b): Probability that a participant is a junior

To find the probability that a randomly selected participant is a junior, we need the total number of juniors:

[ \text{Juniors} = 60 + 20 + 11 = 91 ]

Now, we calculate the probability:

[ P(\text{junior}) = \frac{\text{Number of juniors}}{\text{Total number of students}} = \frac{91}{379} ]

Calculating this gives:

[ P(\text{junior}) \approx 0.240 ]

Rounded to three decimal places:

[ P(\text{junior}) \approx 0.240 ]

Part (d): Probability that a participant is satisfied or a junior

To find (P(\text{satisfied or junior})), we use the formula for the union of two events:

[ P(A \cup B) = P(A) + P(B) - P(A \cap B) ]

Where:

  • (A) is the event of being satisfied.
  • (B) is the event of being a junior.

We already have:

  • (P(A) = P(\text{satisfied}) \approx 0.583)
  • (P(B) = P(\text{junior}) \approx 0.240)

Now we need (P(A \cap B)), which is the probability of being both satisfied and a junior. The number of satisfied juniors is 60.

[ P(A \cap B) = \frac{60}{379} ]

Calculating this gives:

[ P(A \cap B) \approx 0.158 ]

Now we can calculate (P(A \cup B)):

[ P(\text{satisfied or junior}) = P(\text{satisfied}) + P(\text{junior}) - P(\text{satisfied and junior}) ]

Substituting the values:

[ P(\text{satisfied or junior}) \approx 0.583 + 0.240 - 0.158 ]

Calculating this gives:

[ P(\text{satisfied or junior}) \approx 0.665 ]

Rounded to three decimal places:

[ P(\text{satisfied or junior}) \approx 0.665 ]

Summary of Results:

  • (a) (P(\text{satisfied}) \approx 0.583)
  • (b) (P(\text{junior}) \approx 0.240)
  • (d) (P(\text{satisfied or junior}) \approx 0.665)

To solve the problems, we first need to summarize the data provided in the table:

| Class Rank | Satisfied | Neutral | Not Satisfied | Total | |------------|-----------|---------|---------------|-------| | Freshman | 52 | 26 | 21 | 99 | | Sophomore | 52 | 20 | 22 | 94 | | Junior | 60 | 20 | 11 | 91 | | Senior | 57 | 10 | 28 | 95 | | Total | 221 | 76 | 82 | 379 |

Part (a)

To find the probability that a randomly selected participant is satisfied with student government, we use the formula:

[ P(\text{satisfied}) = \frac{\text{Number of satisfied students}}{\text{Total number of students}} ]

From the table, the total number of satisfied students is:

[ 52 + 52 + 60 + 57 = 221 ]

Thus, the probability is:

[ P(\text{satisfied}) = \frac{221}{379} \approx 0.583 ]

Rounded to three decimal places:

[ P(\text{satisfied}) \approx 0.583 ]

Part (b)

To find the probability that a randomly selected participant is a junior, we use the formula:

[ P(\text{junior}) = \frac{\text{Number of juniors}}{\text{Total number of students}} ]

From the table, the total number of juniors is:

[ 91 ]

Thus, the probability is:

[ P(\text{junior}) = \frac{91}{379} \approx 0.240 ]

Rounded to three decimal places:

[ P(\text{junior}) \approx 0.240 ]

Part (c)

To find the probability that a randomly selected participant is both satisfied and a junior, we use the formula:

[ P(\text{satisfied and junior}) = \frac{\text{Number of satisfied juniors}}{\text{Total number of students}} ]

From the table, the number of satisfied juniors is:

[ 60 ]

Thus, the probability is:

[ P(\text{satisfied and junior}) = \frac{60}{379} \approx 0.158 ]

Rounded to three decimal places:

[ P(\text{satisfied and junior}) \approx 0.158 ]

Summary of Answers:

  • (a) ( P(\text{satisfied}) \approx 0.583 )

Probabilities of Home Runs Caught, Dropped, and in a Hat

Let's go through each part step by step.

Part 1

(a) To find the probability that a randomly selected home run is caught by a fan, we use the formula for probability:

[ P(\text{caught by fan}) = \frac{\text{Number of home runs caught by fans}}{\text{Total number of home runs}} ]

Given that 75 out of 1000 home runs were caught by fans:

[ P(\text{caught by fan}) = \frac{75}{1000} = 0.075 ]

Part 2

(b) To find the probability that a randomly selected home run is dropped, we again use the probability formula:

[ P(\text{dropped}) = \frac{\text{Number of home runs dropped}}{\text{Total number of home runs}} ]

Given that 263 out of 1000 home runs were dropped:

[ P(\text{dropped}) = \frac{263}{1000} = 0.263 ]

Part 3

(c) To find the probability that a randomly selected caught ball was caught in a hat, we use the formula:

[ P(\text{caught in hat}) = \frac{\text{Number of home runs caught in a hat}}{\text{Total number of home runs caught}} ]

Given that 2 out of 75 caught balls were caught in a hat:

[ P(\text{caught in hat}) = \frac{2}{75} \approx 0.02667 ]

Interpretation: This probability means that if you randomly select one of the home runs that were caught by fans, there is approximately a 2.67% chance that it was caught in a hat. This indicates that catching a home run in a hat is a relatively rare occurrence compared to other methods of catching, such as using bare hands or gloves.

Summary of Answers:

  • (a) Probability caught by a fan: 0.075
  • (b) Probability dropped: 0.263
  • (c) Probability caught in a hat: 0.02667 (approximately 2.67%)

Calculating Jury Selection Probabilities at a University

To solve the problem, we will use combinations to calculate the probabilities for each part.

Total Combinations

First, we need to calculate the total number of ways to select 6 individuals from the pool of 9 students and 7 faculty (total of 16 individuals).

[ \text{Total combinations} = \binom{16}{6} ]

Calculating this:

[ \binom{16}{6} = \frac{16!}{6!(16-6)!} = \frac{16!}{6! \cdot 10!} = \frac{16 \times 15 \times 14 \times 13 \times 12 \times 11}{6 \times 5 \times 4 \times 3 \times 2 \times 1} = 8008 ]

Part 1: Probability of Selecting a Jury of All Students

To find the probability of selecting a jury of all students (6 students), we calculate the number of ways to choose 6 students from 9.

[ \text{Combinations of all students} = \binom{9}{6} ]

Calculating this:

[ \binom{9}{6} = \binom{9}{3} = \frac{9!}{3!(9-3)!} = \frac{9 \times 8 \times 7}{3 \times 2 \times 1} = 84 ]

Now, the probability of selecting a jury of all students is:

[ P(\text{all students}) = \frac{\text{Combinations of all students}}{\text{Total combinations}} = \frac{84}{8008} \approx 0.01049 ]

Part 2: Probability of Selecting a Jury of All Faculty

To find the probability of selecting a jury of all faculty (6 faculty), we calculate the number of ways to choose 6 faculty from 7.

[ \text{Combinations of all faculty} = \binom{7}{6} ]

Calculating this:

[ \binom{7}{6} = 7 ]

Now, the probability of selecting a jury of all faculty is:

[ P(\text{all faculty}) = \frac{\text{Combinations of all faculty}}{\text{Total combinations}} = \frac{7}{8008} \approx 0.00087 ]

Part 3: Probability of Selecting a Jury of Four Students and Two Faculty

To find the probability of selecting a jury of 4 students and 2 faculty, we calculate the combinations for both groups.

  1. Combinations of 4 students from 9:

[ \text{Combinations of 4 students} = \binom{9}{4} ]

Calculating this:

[ \binom{9}{4} = \frac{9!}{4!(9-4)!} = \frac{9 \times 8 \times 7 \times 6}{4 \times 3 \times 2 \times 1} = 126 ]

  1. Combinations of 2 faculty from 7:

[ \text{Combinations of 2 faculty} = \binom{7}{2} ]

Calculating this:

[ \binom{7}{2} = \frac{7!}{2!(7-2)!} = \frac{7 \times 6}{2 \times 1} = 21 ]

Now, the total combinations for selecting 4 students and 2 faculty is:

[ \text{Total combinations for 4 students and 2 faculty} = \binom{9}{4} \times \binom{7}{2} = 126 \times 21 = 2646 ]

Now, the probability of selecting a jury of 4 students and 2 faculty is:

[ P(4 \text{ students and } 2 \text{ faculty}) = \frac{\text{Total combinations for 4 students and 2 faculty}}{\text{Total combinations}} = \frac{2646}{8008} \approx 0.33049 ]

Final Answers

  • (a) Probability of selecting a jury of all students: 0.01049
  • (b) Probability of selecting a jury of all faculty: 0.00087
  • (c) Probability of selecting a jury of four students and two faculty: 0.33049 (rounded to five decimal places: **0.
