Hi,

p = .19 , n = 120

binomcdf(n, p, largest x-value).

1. what is the probability of getting number 3 twenty times or less

binomcdf(120, .19, 23)= .3024

2.What is the probability of getting the number 3 forty times or more 

1- binomcdf(120, .19, 39)= 1- .9999 = .0001

3.What is the probability of getting the number 3 between twenty and forty times? .9999-.3024

Thanks
