Question

IF N (A) =10, N(B)=9,N(AUB)=14 THEN FIND N (ANB) ​

Answer 1

Answer:

N (AUB)=N(A)+N(B)-N(ANB)

THE ANSWER IS 5

Answer 2

Answer:

n(A n B) = 5

Step-by-step explanation:

Given - n(A) = 10, n(B) = 9, n(A U B) = 14

To Find - n(A n B)

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

Substituting the values we get,

14 = 10 + 9 - n(A n B)

∴n(A n B) = 19 - 14

∴n(A n B) = 5
