Question

Suppose that the random variable xx, shown below, represents the number of speeding tickets a person received in a three-year period. P(x)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.

xx P(x)P(x)
0 0.2956
1 0.2607
2 0.2185
3 0.1683
4 0.0489
5 0.008
6+ 0.0000


a) What is the probability that a randomly selected person has received four or more tickets in a three-year period?

P(x≥4)=

b) What is the probability that a randomly selected person has received more than four tickets in a three-year period?

P(x>4)=
