Question Help About 7% of the population of a large country is allergic to pollen. If two people are randomly selected, what is the probability both are allergic to pollen? What is th probability at least one is allergic to pollen? Assume the events are independent. (a) The probability that both will be allergic to pollen is (Round to four decimal places as needed.)

A variety of preparatory courses are designed to help applicants improve their GMAT scores, which range from 200 to 800. Suppose that a survey of MBA students reveals that among GMAT scorers at least 650, 72% took a preparatory course; whereas among GMAT scores of less than 650 only 31% took a preparatory course. The probability for an applicant to score at least 650 is 30%. Suppose he was not taking the preparatory course. What is his probability of achieving 650 or more for GMAT score? (5…
