What is experimental probability?

Back

Experimental probability is the ratio of the number of times an event occurs to the total number of trials or experiments conducted.

Front

How do you calculate experimental probability?

Back

Experimental probability = (Number of favorable outcomes) / (Total number of trials)

What are the possible values of probability?

Back

Probability can only take values between 0 and 1.

What does a tree diagram represent in probability?

Back

A tree diagram visually represents all possible outcomes of a probability experiment.

Front

How many total outcomes are there when rolling a die and flipping a coin?

Back

12 outcomes (6 outcomes from the die and 2 from the coin: 6 x 2 = 12).
