Well you must have learned the rule at some point, it seems to be standard issue for most stats courses. It's the empirical rule that says for a normal distribution, you can expect $68\%$ of the distribution to fall within one standard deviation of the mean, $95\%$ within two, and $99.7\%$ within three.
