Probability question

OpenStudy (mathmath333):

If 4 digit numbers greater than 5,000 are randomly formed from the digits 0, 1, 3, 5, and 7, what is the probability of forming a number divisible by 5 when the repetition of digits is not allowed?

Parth (parthkohli):

OK, so don't think of it as a probability question. You just have to count the total number of permutations and the number of permutations where the number is divisible by 5. Then you divide them.
