      Glad you found this video helpful! :) yeah, I used to teach for odu, I loved that school :) unfortunately my family had to move, though it's still one of my favorite places I've worked

    why cant we directly do the double integration?

    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)?

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

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

    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??

    • @Stats4Everyone
      @Stats4Everyone  Před 4 lety +1

      Sorry, I am not sure I understand your question. f(x) is the marginal probability distribution. In other words, we can use f(x) to find probabilities that x will have particular values.... so for example, I can say Pr(X < 1) equals the integral of f(x) from 0 to 1.
      This question was asking that we find the expected value of x... in other words, we were finding the value that x takes on average...
      so... say we were to sample from the distribution of x...
      x could be any number between 0 and 2, though it would take some numbers with a higher probability than others based on the distribution, f(x).
      After taking a sample of x's, if I averaged them, I would get 1.5 (which is 3/2).
      Please feel welcome to post a follow-up question.

    I hate math
    Thanks though
