Suppose that the random variable x, shown below, represents the number times . P(x ) 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. P(x) 0 0.4586 1 0.2233 2 0. 1691 3 0.0983 4 0.0423 5 0.0084 6+ 0.0000 a. What is the probability that a randomly selected person has received exactly three tickets in a three-year period? P(x = 3) = 0.0983 b. What is the probability that a randomly selected person has received exactly two tickets in a three- year period? P(x = 2) = 0. 1691 c. What is the probability that that a randomly selected person has received more than two tickets in a three-year period? P(x > 2) = d. What is the probability that that a randomly selected person has received three or less tickets in a three-year period
