Question

If you throw a dice 6 times, what's the chance that you'd get a six on:
a: exactly one of the throws.
b: one or more of the throws

Answer 1

(1/2)^6

Answer 2

a) (5/6)^5*1/6
you need to land on everything EXCEPT 6 5 times out of 6 so 5/6^5 and you need one 1/6 so you multiply it together

b)(1/6)^6
This, you want to only get one all 6 times so 1/6^6


It's just (1/#of possiblities)^(number of "rolls" or trials)
