All 400 employees at an accounting firm indicated what size of vehicle they drive: compact car, mid- size car, large car, or truck. The following table gives a two-way classification of their responses. Compact Car Mid-size Car Large Car Truck 54 48 Male Female 40 51 O b. 0.485, 0.2, 0.65, 0.5294. Management selects one employee at random. Let p₁ be the probability that the employee is a female, p2 the probability that the employee is a male and drives a mid-size car, p3 the probability that the employee is a female or drives a truck, and p4 the probability that the employee is a male knowing that the employee drives a truck. Then the P₁, P2, P3, and P4 are, respectively, (Choose one from the following which is closest to the correct answer.) O c.0.515, 0.2, 0.65, 0.5294. 80 73 O e. 0.515, 0.6675, 0.65, 0.5294.
