Multiplication and Addition principle in probability | Numpy tutorials
The multiplication and addition principles are fundamental concepts in probability theory. The multiplication principle states that when two or more independent events occur sequentially, the probability of the combined outcome is the product of their individual probabilities. This is expressed as P(A and B) = P(A) * P(B).
On the other hand, the addition principle deals with the probability of at least one of two or more mutually exclusive events occurring. For such events, the probability of their combined occurrence is the sum of their individual probabilities. This is expressed as P(A or B) = P(A) + P(B).
Together, these principles provide a framework for calculating probabilities in complex scenarios involving multiple events. They are essential tools in solving problems related to uncertainty and randomness, helping to analyze and predict various outcomes in fields such as statistics, science, and decision-making.
