Let X have the discrete uniform distrubution on the set {1,2,...,N}, where N is a positive integer. Determine the variance of the random variable X. I just don't understand :/

Do you know the formula for the variance of a uniform random variable?
Nope
What class is this from? I can not imagine whatever textbook you are using would not give you the equation for the variance of a random variable especially if they are asking you to computer the variance of a random variable.
