Theoretical probability, also known as classical probability, is a branch of mathematics that deals with determining the likelihood of an event occurring. It calculates the probability of an outcome based on the assumptions that all outcomes are equally likely.

To calculate theoretical probability, you need to determine the number of favorable outcomes and divide it by the total number of possible outcomes. The formula for theoretical probability can be stated as:

P(E) = Number of favorable outcomes / Total number of possible outcomes

Let’s understand this with an example:

Suppose you have a standard six-sided die. You want to calculate the probability of rolling a 3. In this case, the number of favorable outcomes (rolling a 3) is 1, and the total number of possible outcomes (the six sides of the die) is 6. Therefore, the theoretical probability of rolling a 3 is:

P(E) = 1/6

So, the theoretical probability of rolling a 3 is 1 out of 6.

It is important to note that theoretical probability assumes equally likely outcomes, which may not always reflect the actual probability in real-life scenarios. For example, if a die is loaded and more likely to roll a certain number, the theoretical probability may not accurately represent the actual probability. In such cases, experimental or empirical probability is used to calculate the probability based on observed outcomes.
