okay so think of it this way. each chip is labeled with a number, 1-40, right? So, how many of those numbers are a multiple of ten or the number 25 ? only five, right? 10, 20, 30, 40, and the number 25! So, that's 5 chips out of the 40 total. Therefore, the probability is 5/40. This fraction reduced is 1/8. :)
