Question

5. If n(E) = 50, n(A) = 15, n(B) = 13and n(A n B) = 10, find n(A'), n(B') and n(A u B)
​

Answer 1

Answer:

ALL. ARE. EQUAL. FIND AND WRITE

Answer 2

Step-by-step explanation:

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

= 15 + 13 - 10

= 18

n (A') = n(E) - n(A)

= 50 - 15

= 35

n(B') = n(E) - n(B)

= 50 - 13

= 37
