In a certain carnival game, a wheel is divided into thirteen equal parts, of which five are blue and eight are purple. The player spins the wheel until the marker lands on blue or until three spins have occurred. The number of spins is observed. Determine the probability distribution for this experiment. C... Since the outcomes are the numbers of spins, there are three possible outcomes, which are one, two, and three spins. This is illustrated n the tree diagram shown to the right. Determine the probability of spinning the wheel once, which is the marker landed on blue. P(1 spin) = (Type an integer or a simplified fraction.) blue purple 1 Spin blue purple 2 Spins blue or purple -3 Spins

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.
