no. you decrease the probability of infection probablility by probability. i guess i’m not being clear. sorry.
say, three individual measures: mask, gloves, sanitizer gives you a 1/2 chance of infection. then using all three gives you. that’s what i mean, anyway.
1/2*1/2*1/2 = 1/8 = .125 = 12.5% probability of individual infection, instead of a 50% chance of infection.
the probability of non-infection 1-.125 increases to .875 or 87.5%. ok enough said.
Your logic is sort of like wearing a lifejacket in the dessert.
