Question

If n(A)= 5 and n(B)=7 then what is the maximum value of n(A ∩ B)

Answer 1

Answer:

Here's the answer

Step-by-step explanation:

Let us consider n as no. Of elements or morevoff

Then,

We know n(a) =5 and n(b) =7

i.e

n(A U B) =n(A) +n(B)

I.E n(A U B) =5+7

n(A U B) =12

HENCE 12 IS THE RIGHT ANSWER
