Extracted text: Assume that adults have IQ scores that are normally distributed with a mean of 98.4 and a standard deviation of 19.9. Find the probability that a randomly selected adult has an IQ greater than 129.0. (Hint: Draw a graph.) The probability that a randomly selected adult from this group has an IQ greater than 129.0 is (Round to four decimal places as needed.)
