Theoretical probability is a branch of mathematics that deals with the calculation of the likelihood of an event occurring based on logical reasoning and assumptions. It involves using mathematical principles, such as counting techniques, to determine the number of favorable outcomes out of all possible outcomes.

To calculate theoretical probability, we first need to determine the total number of possible outcomes, which depends on the nature of the event or experiment. For example, if we toss a fair six-sided die, the total number of possible outcomes is 6 because there are six different numbers that can appear.

Next, we need to determine the number of favorable outcomes, which are the outcomes that lead to the desired event. Using our previous example, let’s say we want to find the probability of rolling a 3. Since there is only one “3” on the die, the number of favorable outcomes is 1.

Finally, we can calculate the theoretical probability by dividing the number of favorable outcomes by the total number of possible outcomes. In this case, the theoretical probability of rolling a 3 is 1/6, which can also be expressed as a decimal (0.1667) or a percentage (16.67%).

It is important to note that theoretical probability is based on ideal conditions and assumes that all outcomes are equally likely. In practice, actual outcomes may differ due to various factors like randomness, bias, or limitations of the experiment. Therefore, theoretical probability may not always accurately represent real-world situations.
