Question 950579
The lowest possible three digit perfect square is 100, {{{10^2}}}.
{{{sqrt(1000)=31.52}}} so greatest 3 digit perfect square would be {{{31^2}}}=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.
