The number of accidents that occur at the intersection

of Pine and Linden streets between 3 p.m. and

6 p.m. on Friday afternoons is 0, 1, 2, or 3, with probabilities

of 0.84, 0.13, 0.02, and 0.01, respectively.

Graph this probability distribution. What is the

expected value for the random variable given the

number of accidents?
