Question
Suppose that the random variable \( x \), shown below, represents the number of 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. \[ \begin{array}{|c|c|} \hline x & P(x) \\ \hline 0 & 0.2749 \\ 1 & 0.2522 \\ 2 & 0.2511 \\ 3 & 0.1494 \\ 4 & 0.0455 \\ 5 & 0.0269 \\ 6+ & 0.0000 \\ \hline \end{array} \] **Questions:** a) What is the probability that a randomly selected person has received two tickets in a three-year period? \[ P(x = 2) = \] b) What is the probability that a randomly selected person has received four tickets in a three-year period? \[ P(x = 4) = \] c) What is the probability that a randomly selected person has received more than five tickets in a three-year period? \[ P(x > 5) = \] d) What is the probability that a randomly selected person has received three or fewer tickets in a three-year period? \[ P(x \leq 3) = \]
