    Re: Probability

    no of possible outcomes=6*6=36
    now if white die sets 1 then red die has 2,3,4,5,6=5
    white die sets 2 red die has 3,4,5,6=4
    white die sets 3 red die has 4,5,6=3
    white die sets 4 red die has 5,6=2
    white die sets 5 red die has 6=1
    now prob=(5+4+3+2+1)/36=5/12
    Thanks from suhail
