Question

The data on the right represent the number of traffic fatalities by seat location and gender. consider a victim randomly selected from the study.
a. what is the probability that the victim is a malemale​?


b. given that the victim was in the driverdriver ​seat, what is the probability that the victim is a malemale​?

Answer 1

Answer:

The data was unavailable for calculating the probabilities, so the searched data from web is utilized for answering this question.

a. 0.317

b. 0.265

Step-by-step explanation:

The question is incomplete as the data for the question is unavailable. The probability for the given scenario can be calculated by the following data that is taken from web search and is similar to given scenario .

                     Female     Male       Total

Driver          32,740      11,797      44,537

Passenger    6,566       6,412      12,978

Total             39,306     18,209     57,515

a.

P(victim is a male)=P(M)=?

P(M)=n(M)/n(S)

P(M)=18209/57515

P(M)=0.316596

P(M)=0.317  (rounded to 3 decimal places).

Thus, the probability that the victim is a male​ is 0.317.

b.

P(victim is male/victim was in driver seat)=P(M/D)=?

P(M/D)=P(M∩D)/P(D)

P(M∩D)=n(M∩D)/n(S)

P(M∩D)=11797/57515

P(M∩D)=0.2051

P(D)=n(D)/n(S)

P(D)=44537/57515

P(D)=0.7744

P(M/D)=P(M∩D)/P(D)

P(M/D)=0.2051/0.7744

P(M/D)=0.2649

P(M/D)=0.265    (rounded to 3 decimal places).

Thus,  the probability that the victim is a male given that he victim was in the driver seat is 0.265.
