# What Is an Independent Event?

## What Is an Independent Event?

An event is independent if its outcome does not affect the probability of other events occuring.

## Real Examples of Independent Events

It is easier to understand independent events with examples.

### Tossing a Coin

If a coin is tossed, the probability of it landing **Heads** is ** ^{1}⁄_{2}**.

If a coin is tossed a 2^{nd} time, the probability of it landing **Heads** is still ** ^{1}⁄_{2}**.

Each toss does not affect the probability of another toss. Coin tosses are independent events.

### Rolling a Die

If a die is rolled, the probability of getting a **2** is ** ^{1}⁄_{6}**.

If a die is rolled a 2^{nd} time, the probability of getting a **2** is still ** ^{1}⁄_{6}**.

Each die roll does not affect the probability of another roll. Die rolls are independent events.
