Standard Deviation
A fair die is rolled 36 times. What is the standard deviation of the even number (2, 4 or 6) outcomes?
Can someone help me as to point out what formula to use and how to use it?

I did 0.5*36 = 18. Then 18*(1-0.5) = 9. Then square root of 9 which was 3. I'm assuming that is wrong now?
