So i need to find the variance of a number of dice rolls. I know that i use the following formula:(adsbygoogle = window.adsbygoogle || []).push({});

N

∑ ( X i - µ)2

i = 1

σ2 = ---------------

N

but i don't know how to use it. I feel really stupid asking this but i am really lost right now. Thanks for any help in advance.
