The prevalance of mild myopia (nearsightedness) in adults over age 40 is 27% in the US. Suppose eight adults over age 40 are chosen at random from the population; let Y denote the number of adults with mild myopia. Which of the following can be used to find the probability that 3 of them have mild myopia?
