Question

In a large population, 62% of the people have been vaccinated. If 5 people are randomly selected, what is the probability that AT LEAST ONE of them has been vaccinated? Give your answer as a decimal to 3 places.

Answer 1

If we have 5 people, we have

`(5)(0.62)=3.1`

that is, there are 3 of them vaccinated. Then, the probability is

`P(\text{vaccinated)}=(3)/(5)`
