Reference no: EM13120582

Suppose that only 25% of all drivers come to a complete stop at an intersection having flashing red lights in all directions when no other cars are visible. What is the probability that , of 20 randomly chosen drivers coming to an intersection under these conditions,

a) At most 2 will come to a complete stop?
b) At least 2 will come to a complete stop?
c) How many of the next 20 drivers do you expect to come to a complete stop?
