A large 24-hour self-service gas station experiences an average of 1.6 "drive-offs" (gas and dash, where the customer drives away without paying) per week. Assume that these drive-offs occur independently and at random times. Find the probabilities of (a) exactly 2 drive-offs in any given week (b) no drive-offs in any given two week period

A boxcar contains 6 complete car systems. 2/6 are randomly selected for tested and then classified as defective or not defective.   If 2/6 are defective, find the probability that at least one of the systems will be defective.

According to a theory in​ genetics, if tall and colorful plants are crossed with short and colorless​ plants, four types of plants will​ result: tall and​ colorful, tall and​ colorless, short and​ colorful, and short and​ colorless, with corresponding probabilities of 5/16​, 4/16​, 1/16​, and 6/16. In a multinomial​ experiment, if 10 plants are​ selected, find the probability that 3 will be tall and​ colorful, 2 will be tall and​ colorless, 1 will be short and​ colorful, and 4 will be short and colorless.

If a member is selected at random from a finite population, probabilities are identical to?
