Question

In a large population, 67 % of the people have been vaccinated.
If 4 people are randomly selected, what is the probability that AT
LEAST ONE of them has been vaccinated?

Give your answer as a decimal (to at least 3 places) or
fraction

Answer #1

probability that AT LEAST ONE of them has been vaccinated= 1- probability that none of them has been vaccinated

required probability = 1- 0.01186
