5.8. When calculating all the values of a binomial distri- bution, the work can usually be simplified by first calcu- lating b(0; n, 0) and then using the recursion formula o(n -x) b(x + 1; n, 0) = . b(x; n, 0 ) (x + 1) (1 -0) Verify this formula and use it to calculate the values of the binomial distribution with n = 7 and 0 = 0.25
