You can put this solution on YOUR website! A newspaper reported that 5% of Canadian drivers admit to reading the newspaper while driving. If 500 drivers are selected at random, find the probability that exactly 40 will admit to reading the newspaper while driving.
-----
Binomial Problem with n = 500 and p(read) = 0.05
P(x = 40) = 500C40*(0.05)^40*(0.95)^460 = binompdf(500,0.05,40) = 0.0012
= 0.12%
