Side effects: A new medical procedure produces side effects in 20% of the patients who receive it. In a clinical trial, 80 people undergo the procedure. What is the probability that 18 or fewer experience side effects? Approximate using the normal curve. Use the Cumulative Normal Distribution Table or technology. Round your answer to four decimal places. The probability that 18 or fewer patients experience side effects is
