A survey of the types of cars parked at an NFL football stadium revealed that there were equal probabilities of finding cars identified as Type A, B, C, and D. If Type A cars were assigned random numbers 0 through 24, Type B numbers 25 through 49, Type C numbers 50 through 74, and Type D numbers 75 through 99, the sample probability of a Type C car from the 12 random numbers shown below is closest to:
RN: 75, 52, 14, 99, 67, 74, 06, 50, 97, 46, 27, 88
(choose one)
(a) 0.17
(b) 0.25
(c) 0.33
(d) 0.42
Four numbers (52, 67, 74, and 50) are in the range 50 through 74, which indicate type C.
P(Type C) = 4/12 = 0.33
Answer is (c) 0.33
