If n(A)=16, n(B)=13 and n(A U B),read as A union B=22,then find n(A n

1.	If n(A)=16, n(B)=13 and n(A U B),read as A union B=22,then find n(A n B),read as A intersection B.
Answer» Answer: 7 Step-by-step EXPLANATION: N(A U B)=n(A)+n(B)-n(A∩ B) 22=16+13-n(A∩ B) n(A∩ B)=29-22 n(A∩ B)=7

If n(A)=16, n(B)=13 and n(A U B),read as A union B=22,then find n(A n B),read as A intersection B.

Answer»

Answer:

Step-by-step EXPLANATION:

N(A U B)=n(A)+n(B)-n(A∩ B)

22=16+13-n(A∩ B)

n(A∩ B)=29-22

n(A∩ B)=7
