You can put this solution on YOUR website! 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.
A. Graph this probability distribution.
Can't graph that on this site.
----------------------------------------
B. What is the expected value for the random variable given the number of accidents?
E(x) = 0*0.84 + 1*0.13 + 2*0.02 + 3*0.01
E(x) = 0 + 0.13 + 0.04 + 0.03
E(x) = 0.20
