Does the probability of death increase when there are more people?

253 views

Say there is a 1 in 10 chance of death from a virus. My partner suggested that between the two of us, we would have a higher chance of one of us dying. I don’t agree and think that it is still a 1 in 10 chance. But I’m a bit thick when it comes to math…

The standard way to solve this (assuming your chances are independent which is probably not a real assumption) is to reverse it and calculate the probability of you both living. That would be .9 * .9 = .81. Then, the chance of at least one dying is 1 – .81 = .19. This is less then 2/10.
