You 120% right Praet as Manhattan questions are quite tough...

Anyway the stem is not so clear for this one... between "average daily deposit" and "sum of all deposits" I am confused...

The whole thing boils down to: what is the probability that when a prime (above 100) is divided by any number between 1 and 30 will result in a number with fewer than 5 decimal places?

D. 9/30 = 3/10.

favorable#: 1,2,4,5,8,10,16,25, AND 20.

Thanks swath20, though they don't actually post it there (or at least I can't see it there).
