Detailed explanation-1: -The probability that a certain outcome will occur as determined through reasoning or calculation is called theoretical.

Detailed explanation-2: -The theoretical probability is defined as the ratio of the number of favourable outcomes to the number of possible outcomes.

Detailed explanation-3: -Theoretical probability describes how likely an event is to occur. We know that a coin is equally likely to land heads or tails, so the theoretical probability of getting heads is 1/2. Experimental probability describes how frequently an event actually occurred in an experiment.

Detailed explanation-4: -Theoretical probability is probability that is based on an ideal situation. For instance, since a flipped coin has two sides and each side is equally likely to land up, the theoretical probability of landing heads (or tails) is exactly 1 out of 2.

Detailed explanation-5: -An experiment is repeated a fixed number of times and each repetition is known as a trial. Mathematically, the formula for the experimental probability is defined by; Probability of an Event P(E) = Number of times an event occurs / Total number of trials.
