MCQ
જો $A=\left\{1,2,3\right\}, B=\left\{3,5\right\}, C=\left\{2,6\right\}$ હોય, તો $n(\left(A\times\left(B-C\right)\right)=)$ .....
- A$4$
- ✓$6$
- C$9$
- D$12$
$B-C$ = $\left\{3,5\right\}-\left\{2,6\right\}$
= $\left\{3,5\right\}$
= $B$
$n\left(A\times\left(B-C\right)\right) = n\left(A\right)\times n\left(B-C\right)$
= $(3 \times 2)$
= $6$
