Suppose that the random variable xx, shown below, represents the number times . 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. 2

xx P(x)P(x)
0 0.3176
1 0.2705
2 0.2469
3 0.0832
4 0.0485
5 0.0333
6+ 0.0000



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

P(x=4)=P(x=4)=

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

P(x=3)=P(x=3)=

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

P(x>1)=P(x>1)=

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

P(x≤2)=P(x≤2)=
