    integrals

    how do you do given f(y1,y2) - 6(1-y2) for 0<y1<y2<1

    find P(Y1<3/44, Y2>1/2)

    can i know the range for double integrals?

    thanks!

    Please review your posts for typos. There is an obvious one in red. The red minus should be an equal sign.

    Have you drawn the region defined by 0<y1<y2<1? And then, have you drawn inside it the region defined by y2 > 1/2 and y1 < 3/44 (it's a very simple region and makes the limits of integration you need to use crystal clear)?

    (Other things you should do for practice include checking that the given pdf is valid).
