We draw 10 white tiles.
Then we shade in 9 of them.
We count the remaining tiles to get the answer, which is 1.
Answer:To calculate the standard deviation of those numbers:
1.Work out the Mean (the simple average of the numbers)
2.Then for each number: subtract the Mean and square the result.
3.Then work out the mean of those squared differences.
4.Take the square root of that and we are done!
