a^2+b^2=c^2

Well... u build a square in the origin of a XoY axis system with size of 1. On X you have "a" and on Y you have "b". You take the 0.5 points on both axis and unite them. The surface you must not get on is under the line that unites those 2 points.
The probability is just the division between whats left and the whole surface.
Thats how i see it :) (0.875?). If you need details illl post it.

yes 0,875 is correct. Show me a way!

he just showed it?

EDIT:

a = 1
b = 1

percentage = ((a ^ b) - (((a/2) * (a/2)) / 2)) * 100

i won't pic anything.. you can imagine what he said :P
