Question

If ACB, n(A)=4 and n(B)=6 then n(AUB)=

Answer 1

$Given \: A \subset B ,$

$n(A) = 4 \: and \: n(B) = 6$

$\red{ n ( A \cup B ) } \green {= 6}$

Example :

If A = { 1,3 ,5,6} and B = { 1,2,3,4,5,6 }

n(A) = 4, n(B) = 6 , and A is subset of B.

AUB = { 1,3 ,5,6} U { 1,2,3,4,5,6}

= { 1,2,3,4,5,6}

Therefore.,

n(AUB) = 6
