Feb 13, 2020 · Theoretical probability is the likelihood that an event will happen based on pure mathematics. The formula to calculate the theoretical probability of event A happening is: P (A) = number of desired outcomes / total number of possible outcomes. For example, the theoretical probability that a dice lands on “2” after one roll can be ...
Theoretical Probability Definition. Theoretical probability can be defined as the number of favorable outcomes divided by the total number of possible outcomes. To determine the theoretical probability there is no need to conduct an experiment. However, knowledge of the situation is required to find the probability of occurrence of that event.
Probability of Event P(E) = No. of. Favourable outcomes/ No. of. Possible outcomes. Experimental Probability Definition. The experimental probability also is known as an empirical probability, is an approach that relies upon actual experiments and adequate recordings of occurrence of certain events while the theoretical probability attempts to ...

Mathematically: Theoretical Probability = number of outcomes favorable to the event total number of possible outcomes. Carefully read through the following examples. Example 1: Tommy has a bag of candies. There are 5 of candy A, 3 of candy B, and 1 of candy C.
It can be written as the ratio of the number of favorable events divided by the number of possible events. For example, if you have two raffle tickets and 100 tickets were sold: Ratio = number of favorable outcomes / number of possible outcomes = 2/100 = .5. A theoretical probability distribution is a known distribution like the normal ...
For example, if a fair die is rolled 20 times and the number 6 occurs 4 times, then the experimental probability of a 6 on a given roll of the die would be 4/20=1/5. Note that the theoretical probability of a 6 on a given roll would be 1/6, since it is given that the die is fair. So experimental probability can differ from theoretical probability.

The probability of an event is a number between 0 and 1 (inclusive). If the probability of an event is 0, then the event is impossible. On the other hand, an event with probability 1 is certain to occur. In general, the higher the probability of an event, the more likely it is that the event will occur. Example 7.16.
