What is theoretical probability?

Back

Theoretical probability is the likelihood of an event happening based on all possible outcomes, calculated as the number of favorable outcomes divided by the total number of possible outcomes.

How do you calculate the probability of landing on a specific section of a spinner?

Back

To calculate the probability of landing on a specific section of a spinner, divide the number of sections labeled with that outcome by the total number of sections on the spinner.

What is experimental probability?

Back

Experimental probability is the likelihood of an event based on the results of an actual experiment, calculated as the number of times the event occurs divided by the total number of trials.

What is the probability of rolling a number greater than 2 on a 6-sided die?

Back

The probability of rolling a number greater than 2 on a 6-sided die is 2/3, as the favorable outcomes (3, 4, 5, 6) are 4 out of 6 total outcomes.

How do you find the total number of outcomes when making choices?

Back

To find the total number of outcomes when making choices, multiply the number of options for each choice together.

What is the probability of tossing a head first and then a tail when a coin is tossed twice?

Back

The probability of tossing a head first and then a tail is 1/4, as there are four possible outcomes: HH, HT, TH, TT.

Front

What is the formula for calculating probability?

Back

The formula for calculating probability is P(Event) = Number of favorable outcomes / Total number of possible outcomes.

What does it mean if experimental probability is close to theoretical probability?

Back

If experimental probability is close to theoretical probability, it indicates that the experiment is consistent with the expected outcomes based on theoretical calculations.

How many different meals can be designed if customers can choose one entree and one drink from 5 entrees and 5 drinks?

Back

If customers can choose one entree and one drink from 5 options each, the total number of different meals is 5 (entrees) x 5 (drinks) = 25 meals.
