Theoretical Probability

Front

What is theoretical probability?

Back

Theoretical probability is the likelihood of an event occurring based on the possible outcomes in a perfect world, calculated as the ratio of the number of favorable outcomes to the total number of possible outcomes.

Front

How do you calculate the theoretical probability of an event?

Back

Theoretical probability is calculated using the formula: P(Event) = Number of favorable outcomes / Total number of possible outcomes.

What is the theoretical probability of rolling a number greater than 3 on a fair six-sided die?

Back

The theoretical probability is 1/2, as there are 3 favorable outcomes (4, 5, 6) out of 6 possible outcomes.

If a bag contains 5 quarters, 2 dimes, and 4 pennies, what is the total number of coins?

Back

The total number of coins is 11 (5 quarters + 2 dimes + 4 pennies).

What is the probability of picking a quarter from a bag containing 5 quarters, 2 dimes, and 4 pennies?

Back

The probability of picking a quarter is 5/11.

How many possible outcomes are there when spinning a spinner divided into 4 equal sections?

Back

There are 4 possible outcomes when spinning the spinner.

What is the theoretical probability of rolling an 8 on a fair six-sided die?

Back

The theoretical probability of rolling an 8 is 0, as a six-sided die only has numbers 1 through 6.

In a cup containing numbers 1 to 20, how many even numbers are there?

Back

There are 10 even numbers (2, 4, 6, 8, 10, 12, 14, 16, 18, 20) in the range from 1 to 20.

What is the theoretical probability of picking an even number from a cup containing numbers 1 to 20?

Back

The theoretical probability of picking an even number is 1/2, as there are 10 even numbers out of 20 total numbers.

Front

What is the difference between theoretical probability and experimental probability?

Back

Theoretical probability is based on expected outcomes, while experimental probability is based on actual results from experiments.
