Eduncle Mathematical Statistics (USP- Let the binary random variable X have pdf f(x) = p'(1 P) forx = 0,1 Let X independent discrete (0,1) random variables each with probability density function f random variable B = X, + X, +.. +X has a binomial distribution with parameters n andn . The p. The n values of B are b = 0, .., n and represent the number of successes" (i.e., X = 1)in independent trials of an experiment, each with probability p of succesS. Calculate variance af D using the rules of expected values and variances. (B) np(1 + P) (A) np (D) None of the above (C) np(1 p)
