# The expected value of a discrete random variable ‘x’ is given byReview LaterP(x)∑ x P(x)∫ x P(x) dx∑ P(x)

## Question

## Solution 1

The expected value of a discrete random variable 'x' is given by the sum of the product of each outcome and its probability. This can be mathematically represented as:

E(x) = ∑ x P(x)

Here, E(x) represents the expected value, 'x' represents each outcome of the random variable, and P(x) represents Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
