Continuous Random Variables
Finding the Mean, E(X) and the Variance Var(X)
Example
In this next example you are asked to calculate the mean and variance of a continuous random variable. Again it would be a good one to try first and then check your work against the worked solution. I would strongly suggest looking at the video anyway as there is a simple way of finding the mean for this example which you should be aware of.
