minus-squareelvith@feddit.delinkfedilinkarrow-up1·9 months ago9998/10000 is the chance to not get SSPE for a single person. For two persons to not get it (assuming both are infected): 9998/10000 * 9998/1000 For three persons: 9998/10000 * 9998/10000 * 9998/10000 And so on. That means, that the chance for n persons to not get it (no one of them) is (9998/10000)^n That’s where the power comes into play. The other conversion (times 100) is just how percentages work: per cent = per one hundred. So 0.98 = 98/100 = 98%
