What is a Probability Mass Function (PMF) in Statistics?
WebLet X_1,X_2 X 1,X 2 be two random variables with joint pmf p (x_1, x_2) = (1/2)^ {x1+x2} , p(x1,x2) = (1/2)x1+x2, for 1 \leq x _ { i } < \infty , i = 1,2 1 ≤ xi < ∞,i = 1,2 where x_1 x1 … WebMar 7, 2024 · $\begingroup$ Thank you for your answer. Yes, my assumption is that X1 and X2 are independent so it sounds like approach #2 is the correct way of doing things. However I must ask, since I know the entire solution space of Y, why can't I just compute the mean and distribution of all 10,000 Y values i.e instead of using PMFs of X?
