You have a fifty percent chance of scoring higher than the mean.
You have one chance out of three of scoring one standard deviation higher than the mean.
You have one chance out of 22 of scoring two standard deviations higher than the mean.
You have one chance out of 370 of scoring three standard deviations higher than the mean.
You have one chance out of 15,787 of scoring four standard deviations higher than the mean.
You have one chance out of 1,744,278 of scoring five standard deviations higher than the mean.
