Question

if n(A U B) = 8 and n(A intersecting B) = 9 then find n(A) + n(B)​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

answer is 17

Step-by-step explanation:

formula:- n(A U B) = n(A)+n(B)-n(AintersectB)

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

= 8+9

= 17

.

. . n(A)+N(B)= 17
