1. Check that f is a joint probability density function.
2. Calculate the following probabilities:
(a) P(X ≥ 1/2 )
(b) P(X ≤ 1/2,Y ≤ 1/2).
3. Determine the marginal density of X and that of Y.
4. Determine the conditional densities of X and Y.
5. Calculate the conditional expectations of X and Y.

Is it possible to make a step by step solution so k can understand the solving process
Kav10, I have made a mistake setting the deadline. The deadline is actually in 10h hours. Is it still possible for you ?
Let me see what I can do. I am out and will be home in ~5 hours. Can you please give me an exact deadline? Like is it 7 am Eastern Time?
10-11AM Eastern Time
OK. I’ll try to send late tonight!
