It's not the actual accounting but it will be a reasonable estimate. Example: if half of a production run (50%) came with a certain option and only (10%) came with another option, it is reasonable to assume only 5% came with both options. </div></div>

This would be statistically incorrect, as the 50% would have been taken from the total production, as would the 10%. Hence, taking the 50% sample and then applying the 10% figure that was initially derived from the population (total production) would give you an F in statistics class.

By the way, I received an F too at some point, but this I know to be true.
