Hi, if we calculate E(Y) in this question by calculating f(y), will we take 0 - x limits both times, first for f(y) and second time for E(Y)?

Good Work Michelle! thank you! because my book says NOTHING!

THEN HOW WILL WE CALCULATE E(XY) ??, DO WE USE DEPENDENT LIMTIS THERE AS WELL,
??

why cant we directly do the double integration?

Could you do a video on how to derive E (Z|X, Y) ?

In "joint pdf find the constant" video you've take limits of dy as from 0 to 2, but now you're using the limits from 0 to x f(x, y)dy whats the difference, I mean why its not from 0 to 2 for marginal of x

question please
why didnt you put the f(X) answer in the marginal probability??
