Theoretical and Experimental Probability

Front

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.

What is Theoretical Probability?

Back

Theoretical Probability is the ratio of the number of favorable outcomes to the total number of possible outcomes in a given situation.

Front

How do you calculate Experimental Probability?

Back

Experimental Probability = (Number of times the event occurs) / (Total number of trials)

Front

How do you calculate Theoretical Probability?

Back

Theoretical Probability = (Number of favorable outcomes) / (Total number of possible outcomes)

If a die is rolled, what is the theoretical probability of rolling a 1 or 6?

Back

Theoretical Probability = 2/6 or 1/3.

Front

If a die is rolled 14 times and a 1 or 6 is rolled 6 times, what is the experimental probability?

Back

Experimental Probability = 6/14 or 3/7.

What is the total number of outcomes when rolling a die?

Back

The total number of outcomes when rolling a die is 6.

What is the total number of outcomes when selecting a jelly bean from a bag containing 5 green, 2 red, and 3 blue jelly beans?

Back

Total outcomes = 5 + 2 + 3 = 10.
