If our doctors were only 99.9 percent correct, then every year, 4,453,000 prescriptions would be written incorrectly, and probably even scarier, 11 newborns would be given to the wrong parents every day in the United States.
Si els doctors només acertassin un 99,9% de les vegades, cada any hi hauria 4.453.000 medecines mal receptades, i potser encara pitjor, s'entregarien 11 nadons a pares equivocats cada dia als Estats Units.
