If 63 AND 100 are possibilities, which they are, it turns out to be a 38% chance. Easiest way to look at it is to imagine that we're testing a random number 1-100 for being >=1. Obviously there is a 100% chance, even though 100 - 1 = 99. So maybe I should have said to test for the number being just > 63. That would be a 38/101 chance. Best of all would be to have the random number be 1-99 instead of 1-100. Then <=37 would have a 37% chance. Thanks for asking, I hadn't really thought about the math of it. ===== --Aaron Jordan, head programmer of Tmud. __________________________________________________ Do You Yahoo!?
