Understanding Expected Value
Defining Expected Value
Expected value, often denoted as \(E(X)\), is a fundamental concept in probability theory that represents the average or mean value of a random variable. In simple terms, it provides a measure of the central tendency of a probability distribution.
Mathematical Notation
The expected value of a discrete random variable \(X\) is calculated using the formula:
\[ E(X) = \sum_{i} x_i \cdot P(X = x_i) \]
For a continuous random variable, the formula is:
\[ E(X) = \int_{-\infty}^{\infty} x \cdot f(x) \,dx \]
Where:
\( x_i \) represents each possible outcome of the random variable.
\( P(X = x_i) \) is the probability of the corresponding outcome.
\( f(x) \) is the probability density function for continuous random variables.
Significance of Expected Value
1. Central Tendency:
Provides a measure of the central location of a probability distribution.
2. Decision Making:
Guides decision-making processes by indicating the average outcome.
3. Risk Assessment:
Crucial in assessing risks and uncertainties in various fields.

Consider the random variable \(X\) representing the outcome of a fair six-sided die.
The probability distribution is as follows:
\[ P(X = 1) = \frac{1}{6}, \quad P(X = 2)
= \frac{1}{6}, \quad P(X = 3) = \frac{1}{6}, \]
\[ P(X = 4) = \frac{1}{6}, \quad P(X = 5)
= \frac{1}{6}, \quad P(X = 6) = \frac{1}{6} \]
