Question

14.If A and B are two disjoint sets that n(A) = 24,n(B) = 22.Find n(AUB)
and n(A-B).
​

Answer 1

Answer:

$Answer:</p><p>n(AUB) = 46 \: and \: n(A-B) = 24 \\ \\ 1. \: n(AUB) = n(A) + n (B) \\ = 24 + 22 \\ = 46 \\ \\ 2. \: n(A-B) = n(A) -n \\ here \: A \: intersection \: B \: is \: \\ zero , \: \\ because \: it \: is \: a \: disjoint \: \\ and \: there \: is \: no \: \\ common \: elements \: in \: it \: \\ n(A-B) = 24 - 0 \\ therefore \: n(A-B) \: = 24</p><p>.$
