# Given that n(p) = 19, m(P $$\cup$$ Q) = 38 and n(P $$\cap$$ Q) = 7, Find n(C)

### Question

Given that n(p) = 19, m(P $$\cup$$ Q) = 38 and n(P $$\cap$$ Q) = 7, Find n(C)

A) 26

B) 31

C) 36

D) 50

### Explanation:

n(P $$\cup$$ Q) = m(P $$\cap$$ C)

38 = 19 = n(C) - 7

n(C) = 38 - 12

= 26

## Dicussion (1)

• n(P $$\cup$$ Q) = m(P $$\cap$$ C)

38 = 19 = n(C) - 7

n(C) = 38 - 12

= 26
