Find the expected value and variance for each random variable whose probability density function is given. When computing the variance, use formula (5).Let X be a continuous random variable whose values lie between A

and B, and let f(x) be the density function for X. Then,

Let X be a continuous random variable whose values lie between A and B, and let f(x) be the density function for X. Then, Var(X) = x f(x) dx = E(X). - (5)
