Question

If n(A) = 3 and n(B U C ) = 4, then n[(A x B) U (A x C)] is​

Answer 1

Step-by-step explanation:

If n(A) = 3 and n(B U C ) = 4,then

n[(A×B) U (A × C)] is 4

Answer 2

n [(A x B) U (A x C)] is​

Given that, n(A) = 3 and n(B U C ) = 4.

Thus, n [(A x B) U (A x C)] = n [a x(BUC)]

                                            = n(A) x n(BUC)

                                            = 2 x 3

                                             = 6

• The set of elements shared by the specified sets is returned by the intersection method on sets.
• The intersection of sets is represented by the ∩ symbol.
• For example, X ∩ Y can be used to represent the intersection of two sets X and Y.
• The intersection of two sets A and B is the set of all common items, whereas the union of those two sets is the set of all elements that are either in A or in B, or A∪ B.
