Theoretical probability, also known as classical or mathematical probability, is a branch of probability in mathematics that deals with the likelihood of an event occurring based on theoretical calculations. It is based on the assumption that all outcomes of an experiment are equally likely.

To calculate the theoretical probability of an event, you need to understand the total number of possible outcomes and the number of favorable outcomes.

The formula for theoretical probability is:

P(A) = Number of favorable outcomes / Number of possible outcomes

Here, P(A) denotes the probability of event A occurring.

For example, consider a fair six-sided die. The total number of possible outcomes is 6 (since there are six faces on the die, numbered from 1 to 6). Let’s say we want to find the probability of rolling a 2.

Number of favorable outcomes = 1 (as there is only one face with the number 2)
Number of possible outcomes = 6

P(rolling a 2) = 1/6

In this case, the theoretical probability of rolling a 2 is 1/6.

Theoretical probability relies on the assumption that there are no unknown factors or biases affecting the outcomes. It is often used to solve problems and make predictions in various fields, such as mathematics, statistics, physics, and economics.
