Bayes theorem

Two dice are rolled. Below, choose all cases where events $A$ and $B$ are disjoint:

1. $A$: The number of points dropped on the second die is even. $B$: The first die rolled $3$.
2. $A$: The sum of points dropped on both dice is $2$. $B$: The first die rolled $2$.
3. $A$: The number of points dropped on each die is even. $B$: The sum of points dropped on both dice is $7$.
4. $A$: The two dice dropped unequal numbers. $B$: Both numbers are even.
5. $A$: Both dice rolled even numbers. $B$: The product of the numbers is divisible by $8$.
