Experimental and Theoretical 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.

Front

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 successful outcomes) / (Total number of trials)

Front

If a spinner is divided into 4 equal sections, what is the theoretical probability of landing on any one section?

Back

Theoretical probability = 1/4 or 25%.

Front

What is the simplified form of 15/35?

Back

3/7.

Front

If a bag contains 8 jelly beans (2 red, 2 blue, 2 green, 2 yellow), what is the theoretical probability of picking a red jelly bean?

Back

Theoretical probability = 2/8 = 1/4.

Front

What is the difference between experimental and theoretical probability?

Back

Experimental probability is based on actual experiments, while theoretical probability is based on expected outcomes.

Front

If a spinner lands on a number 50 times and lands on '3' 10 times, what is the experimental probability of landing on '3'?

Back

Experimental probability = 10/50 = 1/5.

Front

What is the formula for calculating theoretical probability?

Back

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

Front

If a die is rolled, what is the theoretical probability of rolling a 4?

Back

Theoretical probability = 1/6.
