Answer:

$\frac{4}{9}$

Step-by-step explanation:

To find this probability, we have to know:

How many numbers are there in between 5 and 8 inclusive?
How many total numbers are there?

We simply divide the first answer by the second one and get our probability.

So, the numbers are 5,6,7,8 ----- that is 4 numbers

How many numbers are there in total? That is:

0, 1, 2, 3, 4, 5, 6, 7, 8, or 9 ------- 9 numbers

Thus, the probability is 4/9
