IMAGINE on Big Island there are 100000 old folks and 100000 young folks.
Let’s say the risk of Covid death is .5% for unvaccinated old folks and .1% for vaccinated old folks.
Let’s say the risk of Covid death is .01% for unvaccinated young folks folks and .005% for vaccinated young folks.
Imagine 90% of the old folks get vaccinated and 20% of the young folks get vaccinated.
unvaccinated old dead 10000x.5%=50
unvaccinated young dead 80000x.01%=8
vaccinated old dead 90000x.1%=90
vaccinated young dead 20000x.005%=1
The death toll would be 91 vaccinated, 58 unvaccinated.
The problem is we were told the Pfizer vaccine was 95% effective in preventing a Covid infection in the first place, which is not reflected in your calculations. Your vaccinated old should be (90,000 * .05) * .1% = 4.5 deaths.
IMAGINE you just wasted time doing a bunch a calculations on garbage input numbers and so came up with garbage output numbers. GIGO.
Now IMAGINE how much time and effort you could save by instead borrowing a game number spinner from the kids to come up with bogus, meaningless numbers.
