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.
