Question 912878: Use a normal approximation to find the probability of the indicated number of voters. In this case, assume that 182 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 fewer than 45 voted.
The probability that fewer than 45 of 182 eligible voters voted is ______ (round 4 decimal places)
