A number is selected at random from 1 through 100, inclusive. What is the probability that the number is a multiple of 8?

#1**0 **

this way is probably not the most efficient way to do it, but i just listed out all the multiples of 8 that are between 1 and 100.

here is the list:

8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96.

when you count, there are 12 multiples of 8.

so the answer is 12/100, or 3/25.

another method to solve this is to simply do 100 / 8, which is just 12 remainder 4.

since the quotient is 12, that means there are 12 multiples of 8 in between 1 and 100.

hope this helped! please let me know if you are confused about anything i did
