Question 1145746
p(4) = .4^4 * .6^1 * c(5,4) = .0768 = .077


this is a binomial distribution type problem where p(x) = p^x * q^(n-x) * c(n,x)


n is equal to 5
x ranges from 0 to 5.
c(n,x) = n! / (x! * (n-x)!)


the following excel spreadsheet shows all the probabilities from x = 0 to x = 5.
the sum of all the probabilities is equal to 1, as it should be.
