A die is thrown. A is 'an even number' and B is 'a number greater than 3'.

Explanation

1. 01

   $A = \{2, 4, 6\}$ and $B = \{4, 5, 6\}$. 'A or B' joins them: $\{2, 4, 5, 6\}$; 'A and B' keeps the common part: $\{4, 6\}$.

2. 02

   'A but not B' removes $B$'s outcomes from $A$: $\{2\}$; 'not A' is the odd numbers $\{1, 3, 5\}$.
