Question

Let U denote the universal set and A and B any two sets. if n(U) = 25,
n(A) = 17, n(B) = 7 and n(AUB)' = 2, find the following:
i. n(A)
ii. n(AUB)
iii. n(ANB)
iv. n(A-B)
​

Answer 1

Step-by-step explanation:

n(U)=(A)+(B)-n(ANB) +N(AUB) '

25 =17+7-x+2

(ANB)=1

n(aub) =(a)+(b)-N(ANB)

• 17+7-1
• 24-1

23

n(A)=n(a)-(ANB)

• 17-1

16

n(A-b) =n.(a)

• 16
• if there is mistake then dont mind it

mark me brillantist plzzz
