# What Is a Dependent Event?

## What Is a Dependent Event?

An event is dependent if its probability is affected by whether or not another event has occured.

## A Real Example of a Dependent Event

It is easier to understand a dependent event with an example.

### Picking Cards

If a card is picked from a pack, **1** card is picked from a deck of **52** cards. The probability is ** ^{1}⁄_{52}**.

If the card that has been picked is not put back into the deck, there will be 1 less card in the deck.

If a 2^{nd} card is picked from the deck, **1** card is picked from a deck of **51** cards. The probability is ** ^{1}⁄_{51}**.

Picking cards without replacement are dependent events.
