WebAs we know, if A and B are two events, then the set A ∩ B denotes the event ‘A and B’. Thus, A ∩ B = {x : x ∈ A and x ∈ B} Based on the above expression, we can find the probability of A intersection B. P(A and B) Formula. Consider two events A and B of sample space S, such that their intersection is A ⋂ B. Now, Web16 jun. 2024 · If A and B are two sets, the union of sets A and B (written as A ∪ B) the set of all objects which either belong to A or to B or to both of them. Skip to the content. Search.
