Identifying Independent & Dependent Events Practice

Front

What is an independent event in probability?

Back

An independent event is one where the outcome of one event does not affect the outcome of another event.

Front

What is a dependent event in probability?

Back

A dependent event is one where the outcome of one event affects the outcome of another event.

Example of independent events: Flipping a coin twice. Are these events independent or dependent?

Example of dependent events: Drawing a marble from a bag and not replacing it before drawing another. Are these events independent or dependent?

If you flip a coin and then roll a die, are these events independent or dependent?

Independent

Front

What happens to the probability of drawing a second marble if the first marble is not replaced?

Back

The probability changes because the total number of marbles decreases, making the events dependent.

In the scenario where Tom selects a treat, replaces it, and then selects again, are the selections independent or dependent?

What is the probability of drawing a blue marble after drawing a red marble without replacement?

Back

The probability is dependent on the first draw.
