Probability theory is useful in making predictions that form an important part of research. Why is Probability Theory Used in Statistics? Theoretical probability: Number of favorable outcomes / Number of possible outcomes.Bayes' Theorem: P(A | B) = P(B | A) ⋅ P(A) / P(B).Conditional probability: P(A | B) = P(A∩B) / P(B).Independent events: P(A∩B) = P(A) ⋅ P(B).The main probability theory formulas are as follows: What are the Formulas for Probability Theory? Experimental probability uses repeated experiments to give the probability of an event taking place. Theoretical probability gives the probability of what is expected to happen without conducting any experiments. The two types of probabilities in probability theory are theoretical probability and experimental probability. What are the Two Types of Probabilities in Probability Theory? It encompasses several formal concepts related to probability such as random variables, probability theory distribution, expectation, etc. ![]() Probability theory is a branch of mathematics that deals with the likelihood of occurrence of a random event.
