Joint Probability Density Function and Marginal Density Function

[GOTTT]

Really good video/lecture for understanding the concept of how you can derive Marginal PDFs from Joint PDF's

thank you so much for this amazing video please can I know why we changed the expression from 0<X<1 to 0<x<(1-y) in the last exercice ?

How can i get the joint density function?
Thank you so much :-)

[sarahhope]

but i have learned that we calculate the probability using"" joint cumulative density function""" and not with the""" joint probability density function""
