Conditional probability density function

[edwardsucharda]

Mistake appears in 3:16. The integral should be over dy and not over dx

[mikiallen]

should we multiply by y the conditional density inside the integral ?

[AlexDeSilver]

This is great, however how does the integral (x+y)/((1/2)+x) = 1+4x/4 + 8x ?

Even more thanks to your! Exactly what I needed for it to click in my brain.

Let (X, Y) be Jointly distributed with pdf {(x, y) = {2 0<x<y<1
0 otherwise

then the probability that x>1/5 given y = 2/3

Can u Solve this ?

P(a<=Y<=b|X=x) = integrate fY|X(y|x) dy from a to b
