#### Answer

$\frac{9}{13}$

#### Work Step by Step

We know that $probability=\frac{\text{number of favourable outcomes}}{\text{number of all outcomes}}$ The total number of cards (the number of all outcomes) is $52$. There are $36$ low cards ($9$ in each of the $4$ suits), thus there are $36$ "good outcomes". Hence the probability here is: $\frac{36}{52}=\frac{9}{13}$
