1. Suppose that only 0.21 of all drivers come to a complete stop at an intersection having flashing red lights in all directions when no other cars are visible. 24 randomly chosen drivers coming to an intersection under these conditions. Let X be the number of drivers come to complete stop at an intersection having flashing red lights in all directions. lg USE SALT (a) What is the probability distribution of X. 0 Exponential distribution 0 Normal distribution @ Binomial distribution 0 Poisson distribution [blwhat are the possible values for X? . ...0' 1' 24 O o, 1. ...23 O 1,...23 O 1,...24 [c)What is the probability of exactly 6 will come to a complete stop?
