What did I do wrong? (GRE Math)
Posted 10 January 2013 - 01:21 AM
How many 3-digit positive integers are odd and do not contain the digit 5?
I got 320, but the answer that is given in 288. I just realized that I missed some numbers, but I ended up with 280.
I would greatly appreciate if someone could explain why the answer is 288.

Thank you much. I must have done some miscounting along the way.
