a)not getting 10 sixes

b)all the rolls showing 5 spots or less

I'm not sure how to do either, but for b, I think is it (5/6)^10 because each time there is a chance that the number will be 5 or less?

Please help. thank you!

**PsyDAG**, Wednesday, February 23, 2011 at 1:45ama. Chance of getting 10 sixes = 1/6^10, then getting not sixes = 1 - 1/6^10

b. Same as a, since 5 or less would all be not 6s.
