1. what is the probability of three no.s being all different?

2. And is the opposite of that event two or three no's being the same?

**PsyDAG**, Monday, February 22, 2010 at 6:46am1. You are concerned with

*not*matching the first toss, no matter what it is and not matching the second toss either (5/6*4/6).

2. Again the first toss can be any number. For two the same, you need one the same and one different (1/6*5/6). From that, you should be able to determine the probability of 3 the same. (Either-or probabilities are determined by adding the separate probabilities.)

I hope this helps.
