Question 375154: Please help! Here is the problem:
A particular experiment consists of rolling a fair six-sided die 200 times and counting the number of occurences of three dots showing on the upper face. Determine the probability that three dots will show on the upper face exactly 40 times.
I believe that I'm using the wrong formula and I am stuck!

Hint: This is a binomial experiment with n=200 and p=1/6. You want to find P(X = 40). Let me know if this is enough to get started.
