0 ohm.lumenlearning.com U + Suppose that the random variable z, shown below, represents the number of speeding tickets a person received in a three-year period. 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. 3 P() 0 0.3373 1 0.2943 2 0.2376 3 0.079 4 0.0271 5 0.0247 6+ 0.0000 a) What is the probability that a randomly selected person has received four tickets in a three-year period? Pa = 4) = b) What is the probability that a randomly selected person has received five tickets in a three-year period? Pa = 5) c) What is the probability that that a randomly selected person has received more than two tickets in a three year period? P(> 2) = d) What is the probability that that a randomly selected person has received zero or less tickets in a three-year period? PI< 0) =
