Let X1 and X2 be two random variables following Binomial distribution Bin(n1,p) and Bin(n2,p), respectively. Assume that X1 and X2 are independent.(a) The mgf of binomial distribution Bin(n, p) is (1 p + pet)n. Use this fact to obtain the distribution of X1 + X2.(b) Find the probability P(X1 + X2 = 1|X2 = k) for k = 0 and 1. Then use the law of total probability to find P (X1 + X2 = 1)
