Continuous random variable transformation and marginals

[ricky78]

On the attachment, I was told my joint pdf was right, but the support was NOT 0<y1y2<1 0<y2<1, so maybe it's right now?

Obviously B and C are incorrect, too, since they don't integrate to 1.

I'm probably making just a few simple mistakes. Thanks in advance!

I will look at your work if you type it out; I cannot decipher your attachment, and will not put in the time it would take me to try to read it; it comes out fuzzy and pale, almost unreadable.
