For each combination of answer and choice, specify the number of marks to add or subtract when the student picks it.


$A\cup B$
$A \cap B$
$A\setminus B$

Advice

The union of two sets is the set of elements from either set

$A \cup B = \left\{ x\, |\, x \in A \text{ or } x \in B\right\}$

The intersetction of two sets is the set of elements common to both sets

$A \cap B = \left\{ x\, |\, x \in A \text{ and } x \in B\right\}$

The difference $A-B$ is the set of elements from $A$ which are not in $B$ :

$A - B = \left\{ x \in A |\, x \notin B\right\}$

Similarly, the difference $B-A$ is the set of elements from $B$ which are not in $A$ :

$B - A = \left\{ x \in B |\, x \notin A\right\}$

The symmetric difference $A \Delta B$ is the union of the set differences, but it can also be expressed as the union minus the intersection

$A \Delta B = (A \cup B) - (A \cap B)$ .
