Avalue two standards deviation from the mean is more likely to occur than a value three standard deviations from the mean? true or false?

A value that is two standard deviations from the mean is more likely to occur than a value that is three standard deviations from the mean. Your answer to this question would be True because by the very definition, values that are less standard deviations away from the mean are more likely to occur than values that are more far away from the mean.
