Extracted text: Suppose that the random variable a, shown below, represents the number times . P(r) represents the probability of a randomly selected person having received that number of speeding tickets during that period. Use the probability distribution table shown below to answer the following questions. 17 P(z) 0.2686 1 0.264 2 0.2633 3 0.1363 4 0.0485 5 0.0193 6+ 0.0000 a) What is the probability that a randomly selected person has received three tickets in a three-year period? P(x = 3) = b) What is the probability that a randomly selected person has received one tickets in a three-year period? P(x = 1) =| c) What is the probability that that a randomly selected person has received more than three tickets in a three-year period? P(x > 3) = d) What is the probability that that a randomly selected person has received zero or less tickets in a three- year period? P(x < 0)="">
