## What is the answer of A∩ B?

Case II: (A ∩ B)’ = A’ U B’ Answer: In mathematics, the intersection of two given sets is the largest set that contains all the elements that are common to both the sets. In addition, the symbol for denoting intersection of sets is ∩, which is a common representation of sets.

## What does PA ∩ B ‘) mean?

Joint probability: p(A ∩B). Joint probability is that of event A and event B occurring. It is the probability of the intersection of two or more events. The probability of the intersection of A and B may be written p(A ∩ B). Example: the probability that a card is a four and red =p(four and red) = 2/52=1/26.
