4) An urn contains 8 balls: 4 orange, 3 red, and 1 green. Two balls are selected without replacement. Find: a) P(both balls are orange) %3D b) P(both balls are green) = %3! c) P(both balls are red): %3D d) P(the first ball is orange and the second is green) = e) P(the first ball is red and the second is orange) =. %3D f) P(one is orange and one is green in any order) =. %3D 5) 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 the probability distribution of X is as follows. 1 2 4 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 ux. f) Compute the standard deviation ox.
