Let X and Y be two independent, nonnegative integer-valued random variables whose distribution has the property
P( X=x|X+Y=x+y)= binom m x binom n y binom m+n x+y
for all nonnegative integers x and y where m and n are given positive integers. Assume that P(X = 0) and P(Y = 0) are strictly positive. Show that both X and Y have binomial distributions with the same parameter p, the other parameters being m and n respectively.
