a die is rolled 10 times. find the chance of....
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!

a. 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.
