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 12.

If a coin is tossed a 2nd time, the probability of it landing Heads is still 12.

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 16.

If a die is rolled a 2nd time, the probability of getting a 2 is still 16.

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