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 Â (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 Â Â (rounded to 3 decimal places).
Thus, Â the probability that the victim is a male given that he victim was in the driver seat is 0.265.
Using the concept of direct and conditional probability, the probability that :
- Victim is male = 0.3166
- Victim is male given that victim was in driver's seat is 0.2649
Recall :
- Probability = required outcome / Total possible outcomes
1.) Probability that victim is male :
- P(male) = Number of male victims / total passengers
- P(male) = 18209 / 57515 = 0.3166
2.) Probability of male given that victim was in the driver's seat :
- Recall conditional probability :
- P(A|B) = P(AnB) / P(B)
- P(male | driver's seat) = P(male n driver's seat) / P(driver's seat)
- P(male|driver's seat) = 11797 / 44537 = 0.2649
Therefore,
- P(male) = 0.3166
- P(male|driver's seat) = 0.2649
