Solution

The correct option is D
n(U) - n(A U B)

No of elements not in set A and not in set B is represented in set notation as A^I ∩ B^I.

So, n(A^I ∩ B^I) = n(A U B)^I

= n(U) - n(A U B)

The correct option is D n(U) - n(A U B) No of elements not in set A and not in set B is represented in set notation as AI ∩ BI. So, n(AI ∩ BI) = n(A U B)I = n(U) - n(A U B)

The correct option is D
n(U) - n(A U B)

No of elements not in set A and not in set B is represented in set notation as A^I ∩ B^I.

So, n(A^I ∩ B^I) = n(A U B)^I

= n(U) - n(A U B)
