Notes and Ideas: §

The expected values E(X),E(X2),E(X3),…,and E(Xr) are called moments. since we know that and Which are functioons of moments, are someimtes difficult to find. We use moment-generating function to find moments and functions of moments, such as and

Let X be a duscrete radom varaible with probability mass function f(x) and support S, then:
