Pedro has a number cube with 24 faces and an integer between 1 and 24 on each face. Every number is featured exactly once. When he rolls, what is the probability that the number showing is a factor of 24?

As per the solution, a number of faces taken as 24. Then what about "between" mentioned in the question. Between 1 and 24 means, there should be 22 faces. Isn't it?

Both 1 and 24 are included!

This is quite poorly worded question. Please share the source

Factors of 24 are = 1, 2, 3, 4, 6, 8, 12, 24.

So probability becomes = $$\frac{8}{24}$$
