Photos - Question 19.png ✓ Fullscreen 88 ? Use a normal approximation to find the probability of the indicated number of voters. In this case, assume that 143 eligible voters aged 18-24 are randomly selected. Suppose a previous study showed that am eligible voters aged 18-24, 22% of them voted. Probability that fewer than 34 voted The probability that fewer than 34 of 143 eligible voters voted is (Round to four decimal places as needed.) 8:41 AM 65°F ww 4/29/2022 Sunny ■ i H F C 0 3 B 7
