WebIn probability, there is only a chance for a success (likelihood of an event to happen) or a failure (likelihood of an event not to happen). The sum of all probabilities in an event add up to 1. ‘Or’ in probability means addition while ‘and’ means multiplication. Formula to calculate probability P (A). Example 1. WebP(A∩B) is the probability of both independent events “A” and "B" happening together. The symbol "∩" means intersection. This formula is used to quickly predict the result. When events are independent, we can use the multiplication rule, which states that the two events A and B are independent if the occurrence of one event does not change the probability of … fisher price little people animal playset
