So it could be 15 injuries and 5 COVID cases?

Indeed. Or 1 COVID case, and 19 injuries, Or 2 COVID cases, and 18 injuries. Or 3 COVID cases, and 17 injuries. Or 4 COVID cases, and 16 injuries. Or 6 COVID cases, and 14 injuries. Or 7 COVID cases, and 13 injuries. Or 8 COVID cases, and 12 injuries. Or 9 COVID cases, and 11 injuries. Or 10 COVID cases, and 10 injuries. Or 11 COVID cases, and 9 injuries. Or 12 COVID cases, and 8 injuries. Or 13 COVID cases, and 7 injuries. Or 14 COVID cases, and 6 injuries. Or 15 COVID cases, and 5 injuries. Or 16 COVID cases, and 4 injuries. Or 17 COVID cases, and 3 injuries. Or 18 COVID cases, and 2 injuries. Or 19 COVID cases, and 1 injury.

On the other hand, it could be 20 COVID cases and no injuries...or zero COVID cases and all injuries. I'm not sure.
