That should be:
12,755 deaths/
(91,540 recovered+12,755 deaths)
⇒12.2%
Sorry. I'm pretty fried...
No. The statistic is this “Out of the confirmed cases, what percentage of cases have died?” Clearly adding the recovered to the dead makes no sense from a data standpoint.
You can divide Recovered by Confirmed and get “”Out of the confirmed cases, what percentage of cases have recovered?”
Your stat is “Out of the recovered and dead cases, what percentage of cases have died?” Deaths are occurring in the confirmed cases, not the recovered cases.
