Question

n(B)formula. and. n(U)

Answer 1

2, 3, 4} and B= {2, 4, 5, 6, 7, 8} The intersection (elements in the two sets) of these two setsis n(A∩B)={2,4} (a) The formula n(A U B) = n(

Answer 2

solution

✴n(A union B)= n(A)+ n(B) - n(A intersection B)


✴n(B)= n(A union B)+ n(A intersection B) - n(A)
