what's the probability of picking any number?

how many ways can you pick a number divisible by 5

Here is a vocabulary lesson.

If one says "integers from one to thirty" means $\displaystyle 1\le n\le 30$.

If one says "integers between one to thirty" means $\displaystyle 1< n< 30$.

Now to answer question is: $\displaystyle \frac{{\left\lfloor {\frac{{30}}{5}} \right\rfloor }}{{30}} = \frac{1}{5}$
