Use a normal approximation to find the probability of the indicated number of voters. In this case, assume that 189 eligible voters aged 18-24 are randomly select Suppose a previous study showed that among eligible voters aged 18-24, 22% of them voted. Probability that fewer than 46 voted The probability that fewer than 46 of 189 eligible voters voted is (Round to four decimal places as needed.)
