moment generating function, mgf of binomial distrbution

* *

******* 1 1 |
find the mgf of the
binomial distribution and hence deduce the mean and variance ---------------------------------------------- ----------------------------------------------- mgf is expectation of e^(tx) since the distribution is discrete use summation for mean , differentiate the mgf w.r.t t and then put t=0 for second raw moment ,differentiate the mgf twice w.r.t t and then put t=0 answer and some steps are given below ================ * * ================ mean of the poisson distribution ------mean of the poisson distribution mean and variance of the discrete uniform distribution f(x) = 1/k , x = 1,2,...k mean and variance of discrete uniform integration formulae problems on integration |
