X,Y are normal distributed iid............P(x>0|X+y>0)=?

Do you want a hint or do you just want me to show you how to do the problem?

 

[Stavhaco]

Start with a hint

 

[Steven G]

X+Y>0 implies that X>-Y. Now since X and Y are normal distributed then p(X>|a|) = p(Y<|a|)

Can you post full solution?
