44. Do you carpool? Let X represent the number of occupants in a randomly chosen car on a certain stretch of highway during morning commute hours. A survey of cars showed that t probability distribution of X is as follows. X 1 2 3 4 5 P(x) 0.70 0.15 0.10 0.03 0.02 a. Find P (2). b. Find P (More than 3). c. Find the probability that a car has only one occupant. d. Find the probability that a car has fewer than four occupants. e. Compute the mean x. f. Compute the standard deviation ox. g. To save energy, a goal is set to have the mean number of occupants be at least two Has this goal been met?
