Answer
$\frac{5}{6}$
Work Step by Step
We know that $probability=\frac{\text{number of favourable outcomes}}{\text{number of all outcomes}}$
The number of all outcomes is $6$
The good outcomes are landing on $1,3,4,5,6$, thus there are $5$ "good outcomes".
Hence the probability here is: $\frac{5}{6}$
