Hi! I'm new here and sure that you guys are able to help me out. I've got stuck with this assignment that I don't know how to solve. My problem is that I don't know what limits I should use for the integrals.

You can see the problem here:

a) Find P(Y1 < 2, Y2>1)

I found the right answer to this one, but there are also a B- and a C-assignment, which I don't know how to solve.

b) Find P(Y1> or equal to 2Y2)

The correct answer is 1/2.

c) P(Y1-Y2> or equal to 1)

The correct answer in this is e^-y1

Can you please show how to limit the integrals as well?

Thanks a lot!
