Expected Value Calculator

Formula

The formula to calculate the Expected Value (EV) is:

\[ EV = P(x) \times n \]

Where:

\(EV\) is the expected value of the expected number of successes
\(P(x)\) is the probability of event \(x\) occurring
\(n\) is the number of trials

Expected Value Definition

An expected value is the sum of the probability of an event occurring and the number of trials performed. It measures the average outcome if the experiment were repeated many times.

Example Calculation

Let's assume the following values:

Probability of Event (P(x)) = 0.3
Number of Trials (n) = 50

Using the formula to calculate the Expected Value (EV):

\[ EV = P(x) \times n = 0.3 \times 50 = 15 \]

The Expected Value (EV) is 15.
