About 1% of the American population is allergic to peanuts or tree nuts. Select three individuals at random and let the random variable X be the number in this sample who are allergic to peanuts or tree nuts. The possible values which X can take are 0, 1, 2, and 3. Determine the conditional probability that exactly 2 of the people will be allergic to peanuts or tree nuts, given that at least 1 of the 3 people suffers from one of these allergies? (Round your answer to four decimal places.)
