1. Find the maximum likelihood estimator (MLE) of the unknown parameter based on a random sample X,..., X, from each of the following distributions: (a) X, ~ BIN(1, P) . (b) X; ~ GEO(p) . (c) X, ~ N(O, 0). (d) X; ~ GAM(2, 0) . (e) X, ~ WEI(0,1/2) . (Note: f(x) = abx exp(-ax ), x >0.a &b are positive parameters. Here a=0 , b=1/2)
