The lowest possible three digit perfect square is 100, 10%5E2.
sqrt%281000%29=31.52 so greatest 3 digit perfect square would be 31%5E2=961
The three digit perfect squares would be squares of integers 10 to 31 for a total of 22 perfect squares. There are 900 three digit integers from 100 to 999, so the chance of picking a perfect square is 22 in 900.
