Q 2; Write down the comprehensive comparative analysis about the Binomial, Multinomial, Negative binomial and Geometric distributions in discrete case. (Note: all the comparisons must be in tabulated format with meaningful headings.) Q 3; Let X and Y be independent random variables such that prob. 1/3 2 prob. 3/4 x = 10 prob. 2/3 Y = -3 prob. 1/4 Find (a) E(3X+2Y), (b) E(2X^2 - Y^2), (c) E(XY), (d) E(X^2 Y)
