Thomas Sepulchre comments on A decision tree for vaccinating children against Covid-19, or how to wisely make a monumental decision

[Thomas Sepulchre]

You have to replace the right term $599.976$ by $599.9976$. This makes the sum equal to $600.000079976$, or $600.00$ if you keep only two digits after the decimal point. Still pretty close to 600 though :)

Thanks! I’ve updated the calculation and diagram.
