Probability distribution for x+y
Webb27 okt. 2024 · The Probability Function of a discrete random variable X is the function p (x) satisfying p (x) = Pr (X = x) Let’s look at an example: Question: We draw two cards … WebbWe have a joint probability of Pr(x=1, y=1), x=1 meaning the chance of raining, y=1 meaning you have an umbrella. The Case 2 is a worst case scenario. It rains and you don’t have an umbrella.
