moment generating function,  mgf of binomial distrbution
* *



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
