    If 'p', 'q' and 'n' are probability pf success, failure and number of trials respectively in a Binomial Distribution, what is its Standard Deviation?

    √ (np)2 √np √pq √npq

    For a binomial probability distribution; the probability of failure is 2/3 and variance is 40/9. The number of independent trials is _______________.

    4 40 20 5/4

    Hypergeometric probability of hypergeometric distribution function is given by the formula _________

    h(x; N, n, k) = [kCx] [N-kCn-x] / [NCn]

    h(x; N, n, k) = [kCx] [N-kCn] / [NCn]

    h(x; N, n, k) = [kCx] [NCn-x] / [NCn]

    h(x; N, n, k) = [kCx] [N-kCn-x] / [N-kCn]

    If Mean = 4 and p = 1/3 than the value of independent trials, variance and Standard deviation is:

    12, 8/3, 13/8 12, 3/13, 8/13 12, 8/3, 8/13 12, 3/8, 13/8

    The p.d.f of Poisson Distribution is given by ___________
