Probability of x+y

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. Given two random variables that are defined on the same probability space, the joint probability distribution is the corresponding probability distribution on all possible pairs of outputs. The joint distribution can just as well be considered for any given number of random variables. The joint distribution encodes the marginal distributions, i.e. the distributions of each of the individual random va…
