Use a normal approximation to find the probability of the indicated number of voters. In this​ case, assume that 137 eligible voters aged​ 18-24 are randomly selected. Suppose a previous study showed that among eligible voters aged​ 18-24, 22% of them voted.   Probability that fewer than 35 voted The probability that fewer than 35 of 137 eligible voters voted is nothing.
