You would have to do (1/6)(1/6)(1/6) to get your answer.
That would be the probability of rolling a 3 three times though, i'm looking for the probability of rolling at LEAST one 3.
It would be A(prime) = 1 - (1/6)^3
= 216/216 - 1/216
That's the probability of not rolling a 3 three times in a row.
Btw, the answer is supposed to be 91/216.
First,find the probability that no six occurs in 3 throws,which will be equal to
Therefore the probability that at least one six occurs will be

LOL, I forgot that dice is plural.
Thanks for the help though guys!
