Question

if n(A)=10,n(B)=12 and n(A∩B)=6 then find n(AU B)​

Answer 1

Answer:

Pls mark me as brainliest

Step-by-step explanation:

n(A)=10,n(B)=12 and n(A∩B)=6

n(AUB) = n(A) + n(B) - n(A∩B) = 22 - 6 = 16

Answer 2

Answer:

16

Step-by-step explanation:

Dear student,

We know that n(A U B) = n(A) + n(B) - n(A Π B)

Now by substituting the values we get:

n ( AUB)= 10+12-6

= 22-6

= 16

Hope this helps you!!

If it did please mark it as brainliest!!!

Cheers.
