Question

You have the numbers 1-25 written on slips of paper. if you choose one slip at random, what is the probability that you will select a number that is divisible by 5?

3/5
4/25
1/5
8/25

Answer 1

5, 10, 15, 20, 25

There are 5 numbers that are divisible by 5.

P(Div by 5) = 5/25 = 1/5

Answer 2

To determine how many numbers from 1-25 that can be divisible by 5, let's count the multiples of 5 that go to 25.

5, 10, 15, 20, 25.

There are 5 multiples of 5 that are contained in 1-25.

Our current fraction is 5/25, as we have 5 multiples of 5, and 25 total numbers.

Since we don't have an answer choice that matches our answer, we may need to simplify.

Divide both sides by 5.

5 / 5 = 1
25 / 5 = 5

Our new and simplified answer is 1/5.

Your answer is C.) 1/5.

I hope this helps!
