The joint probability mass function of (x,y) is given by P(X=x,Y=y)=k(2x+3y), X=0,1,2: Y = 1,2,3. Find k, marginal probability distribution of X and Y. Also find conditional probability distribution of X for Y=1. i.e. $P\left[\frac{X=x}{Y=1}\right]$ RTU B.Tech Statistics and Probability Theory 2013
