## Homework Statement

The probability that a person picked at random is 85 years old is 0.008 . if two people are picked at random find the probability of that:

a. they are both 85

b. neither is 85

c. at least one is 85

I have two questions like this one and I am so confused as to how you would find the answer if you aren't given the pool size. could you show me how one would work this problem out?

Thanks :)
