compute the 3 probabilities for the following:

a) at least one 6 when 6 dice are rolled

b) at least two 6s when 12 dice are rolled

c) at least three 6s when 18 dice are rolled.

I'm not sure if I should be using the multiplication or addition rule or if there is some other way of calculating. I think this relates to the idea of complements since it has the "at least one" statement. I wonder if I could just get the hint as to which formula to use? Could this be figured out as a binomial distribution? i.e. X~Binomial(n=6, p=.167)
