the question says:

How many integers from 1 thorugh 100 must you pick in order to be sure of getting one that is divisble by 5?

Well i just started writing out the numbers

1,2,3,4,5,...

now 5/5 = 1, remainder of 0, so its divisible by 5.

So is it simply you must pick 5 integers start at 1 to ensure of getting one that is divisble by 5.
