If set $A=\{1,2,3,4\}$ and $B=\{3,4,5,6\}$. Find $A-B$. |
$\{1,2,3,4,5,6\}$ $\{3,4\}$ $\{1,2\}$ $\{5,6\}$ |
$\{1,2\}$ |
The correct answer is Option (3) → $\{1,2\}$ $A-B$ is the set of elements that belongs to A but not to B. Here, 1 and 2 belongs to A but not to B. So, $A = \{1,2,3,4\}$ $B = \{3,4,5,6\}$ $A – B = \{1,2,3,4\} – \{3,4,5,6\} = \{1,2\}$. |
