**drwls**, Monday, January 14, 2013 at 1:16pmThe numbers are between 100 and 999. There are 900 numbers to choose from.

450 of those numbers are divisible by 2. They are:

102, 104, 106, 108, ... 997, and 999

Of that group of 450 numbers, every third number is divisible by 3.

Thus, 150 numbers are divisible by 2 AND 3, and 300 numbers are divisible by 2 BUT NOT 3.

The probability of the latter situation is 300/900 = 1/3.
