Theoretical vs 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 conducted.

Front

How do you calculate experimental probability?

Back

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

Front

What is theoretical probability?

Back

Theoretical probability is the likelihood of an event occurring based on all possible outcomes, calculated as the ratio of favorable outcomes to total outcomes.

Front

How do you calculate 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

The theoretical probability of rolling a 4 is 1/6.

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

What is the probability of an event expressed as?

Back

The probability of an event can be expressed as a fraction, decimal, or percent.

Front

If an event occurs 5 times in 20 trials, what is the experimental probability?

Back

The experimental probability is 5/20 or 1/4.

Front

What is the experimental probability of spinning a spinner that lands on a number 3, if it landed on 3 out of 10 spins?

Back

The experimental probability is 3/10 or 30%.

Front

What does it mean if the experimental probability of an event is close to the theoretical probability?

Back

It indicates that the experiment is consistent with the expected outcomes.
