V Suppose that 18% of the people in a large city have used a hospital emergency room in the past year. If a random samplj of 115 people from the city is taken, approximate the probability that fewer than 22 used an emergency room in the past year. Use the normal approximation to the binomial with a correction for continuity. Round your answer to at least three decimal places. Do not round any intermediate steps. (If necessary, consult a list of formulas.) [I] x s
