WebExplanation for the correct option: Given, A and B are 2 sets. From the Venn diagram, we can see that the set B - A contains no elements from the set A. Therefore, the intersection of the 2 sets A and B - A that is A ∩ ( B – A) will be a null set ϕ. Hence, Option ‘A’ is Correct. Suggest Corrections. 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.
