Substituting appropriate values for x and y into the formula of Theorem 9, show that n (a) > 2": r=0 (b) -1 = 0; r=0 (c) (a r=0 the number of ways in which we can choose the one factor providing the y, and the ) = 1 and () = 1. %3D coefficients of x and y are ( More generally, if n is a positive integer and we multiply out (x+y)" term by term, the coefficient of x"-ry is ("), the number of ways in which we can choose (の) as a binomial coefficient. the r factors providing the y's. Accordingly, we refer to 0,1,...,20 and r 0,1,..., 10 are given Values of the binomial coefficients for n = in table Factorials and Binomial Coefficients of "Statistical Tables."
