Question 910447: The proportion of individuals insured by the All-Driver Automobile Insurance Co. who received at least one traffic ticket during a five-year period is 0.13.
If 140 insured individuals are randomly selected, what is the probability that between 10 and 27 of them have received at least one ticket?

p = .13, n = 140
p(x ≤ 27) = binomcdf(140, .13, 27)
P(x ≤ 10) = binomcdf(140, .13, 10)
P(10 < x< 27) = binomcdf(140, .13, 27) - binomcdf(140, .13, 10)
