Webb8 nov. 2024 · Consider the following two experiments: the first has outcome X taking on the values 0, 1, and 2 with equal probabilities; the second results in an (independent) outcome Y taking on the value 3 with probability 1/4 and 4 with probability 3/4. Find the distribution of (7.1.13) ( a) Y + X ( b) Y − X 7.1. 6 WebbSolution We can use the formula: h ( y x) = f ( x, y) f X ( x) to find the conditional p.d.f. of Y given X. But, to do so, we clearly have to find f X ( x), the marginal p.d.f. of X first. Recall that we can do that by integrating the joint p.d.f. f ( x, y) over S 2, the support of Y. Here's what the joint support S looks like: y x 1 1 y=x 2

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.
