I have no idea where you found a friend dumb enough to make this bet, but you win by telling him you'll give him 10-1 odds every time kobe steps to the line. The other BS about another laker being able to hit DOES help, but essentially, you need to figure 14.8%(kobe's incedence of missing)x 14.8% to see how often he misses both.
14.8% x 14.8%=2.2%
So, essentially, you could give him 45-1 odds, and still have the best of it.
