Experimental and Theoretical Probability Practice

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 likelihood of an event happening based on all possible outcomes, calculated using the formula: P(Event) = Number of favorable outcomes / Total number of outcomes.

If a number cube is rolled 20 times and lands on 3 six times, what is the experimental probability of rolling a 3?

Front

What happens to experimental probability as the number of trials increases?

Back

As the number of trials increases, the experimental probability tends to get closer to the theoretical probability.

What is the formula for calculating experimental probability?

Back

The formula for experimental probability is: P(Event) = Number of times the event occurs / Total number of trials.

In 180 school days, how many times would you expect a girl to be selected if there are 12 girls and 8 boys?

Back

You would expect a girl to be selected approximately 108 times.

Front

What is the relationship between experimental and theoretical probability?

Back

Experimental probability is based on actual experiments, while theoretical probability is based on expected outcomes. They may differ, especially with fewer trials.
