    3 hrs of struggle, and this video uses 30 sec to make joke of my life. 30 sec from this video is all i need.

    Thank you so much. You are truly a life saver. I have a deadline in 15 hours but I have no idea how to do it, nor that I have a single clue from my book. But you saved me, now I understand how to choose my bound from the picture of my support. Thank you!

    I still don't understand how to determine the ranges for x and y and why they change when calculating marginal pdfs and when calculating expectation 😢

  • @medolab-e3n

    In example 4 why is that you didnt make use of lower limit of y=0 and upper limit of y=1 while calculating the value of k whereas range of 0 to 1 was used for x?

    How you have taken the limits fom y to 1

    k/8 = 1/2 isn't it? Because The value of our area is 1/2. Could you please explain it ?
    Thank you so much for this helpful video

    Thanks for your lecture. Could you please explain me for the following function. Find the value of k for the function f(x,y)=kxy^2 if 0≦x≦y≦1

    Really helpful! Thank you!!
    Could you please explain explain the following questions...
    P(X=x,Y=y)= c(xy+x+1)
    where x=0,1,2 and y=0,1. no other values are possible.
    (a) show that c= 1/15 makes this a valid probability distribution.
    (b) find the marginal distribution of X and also E (X).
    (c) find the conditional distribution of X given that Y=1 and evaluate it's mean.

    If you could slow down just a little it would be super helpful! I guess you are limited to a 10-minute video...
