one of the set of r.v.'s constituting Y. discrete random vector (Y₁, Y2), the marginal distribution for one r.v. is found by summing joint probabilities.

Joint and Conditional Distributions: First consider the case when X and Y are both discrete. Then the marginal pdf's (or pmf's. = probability mass functions, if ...

One way to remember these is by saying the words: the conditional distribution is the joint distribution divided by the marginal distribution. Also notice the ...

The marginal distribution tells us what we would expect to see overall. Now, restrict the view to a specific characteristic (the condition we are placing on a ...

Q1) The joint probability function of two discrete random variables X and Y is given by f(x,y) = cxy for x = 1,2,3 and y = 1,2,3 and equals zero otherwise.

Note that we only need to integrate over the support of the distribution because the PDF is 0 elsewhere. So c = 21/4. How did I get these limits of integration?

How are these related? • To find the marginal pmf of X, we use the law of total probability. pX(x) = X.
