f is distributed normal. a quick update- i did calculate the inner integral in terms of the error function. and as the f is gaussian, I'm hoping that a closed form solution will emerge.i just need a clever way to prove that the net result is positive. also this is not a homework problem.

I need help proving that the following (double) integral is positive: int(limits from -infinity to +infinity) f(b) int(limits from b to +infinity) [e^{-(x-mean)/(2 *variance)}]/sq root(2 *pi *variance) dx db thanks
