**Lesson 8 Mathematical Expectation STAT 414 / 415**

Mathematical Expectation is an important concept in Probability Theory. Mathematically, for a discrete variable X with probability function P(X), the expected value E[X] is given by Σ x i P(x i ) the summation runs over all the distinct values x i that the variable can take.... Mathematical Expectation is an important concept in Probability Theory.

The mathematical expectation will be given by the mathematical formula as, E(X)= Σ (x 1 p 1, x 2 p 2, …, x n p n), where x is a random variable with the probability function, f(x), p is the probability of the occurrence, and n is the number of all possible values In the case...

**Mathematical Expectation for Joint Probability**

Mathematical Expectation is an important concept in Probability Theory. Mathematically, for a discrete variable X with probability function P(X), the expected value E[X] is given by Σ x i P(x i ) the summation runs over all the distinct values x i that the variable can take. pdf introduction to mathematical statistics Expectation and Variance The expected value (or mean) of X, where X is a discrete random variable, is a weighted average of the possible values that X can take, each value being weighted according to the probability of that event occurring.

the observation that there are n ways to choose the ﬁrst item (in our example, 1, 2 or 3), n− 1 ways to choose the second item (once the ﬁrst item has been eliminated) and so on.

- Mathematics expectation is useful in our daily life it makes our life easier, from using mathematics expectation we can easily take our decision and we can predict result to a certain limit.
