Question 920352
honest die , p(one) = 1/6, p(not one) = 5/6,   n = 180
x the number of one's
TI syntax is binomcdf(n, p, largest x-value) for binomial ≤  cumulative probability
P(x > 30) = 1 - binomcdf(150, 1/6, 30)
P(20 < x < 40) =   binomcdf(150, 1/6, 39)- binomcdf(150, 1/6, 19)
P(x < 15) =  binomcdf(150, 1/6, 14)
