    When choosing limits to evaluate integrals, when do you choose constants and when do you choose a function of the other variable? So for the joint CDF it seems the inner integral is always in terms of the other variable, but what about for finding probabilities like P(X+Y>3) or finding the marginal probability functions?

    It depends on what the random variables are, there isn't really a one method fits all.
