See explanation.

Explanation:

There are 6 possible results of a throw.

In the first part there is only 1 result fulfilling the condition: $6$, so the probability is $\frac{1}{6}$.

The second part has 2 results satisfying the condition.

$B = \left\{5 , 6\right\}$

So the probability is:

$P \left(B\right) = \frac{2}{6} = \frac{1}{3}$
