If n (A-B) = 12. (AUB) = 35 and n (B – A) = 15 then find n(AnB)?​

Answer»

Answer:

N(AnB) = 8

Step-by-step explanation:

n(B) = n(AUB) - n(A-B)

= 35 - 12

= 23

n(A) = n(AUB) - n(B-A)

= 35 - 15

= 20

Now the formula, n(AUB) = n(A) + n(B) - n(AnB)

35 = 20 + 23 - n(AnB)

n(AnB) = 8

HOPE THIS HELPS YOU.....
