According to a posting on a website subsequent to the death of a child who bit into a peanut, a certain study found that 6% of children younger than 18 in the United States have at least one food allergy. Among those with food allergies, about 41% had a history of severe reaction. (a) If a child younger than 18 is randomly selected, what is the probability that he or she has at least one food allergy and a history of severe reaction? (Enter your answer to four decimal places.) (b) It was also reported that 30% of those with an allergy in fact are allergic to multiple foods. If a child younger than 18 is randomly selected, what is the probability that he or she is allergic to multiple foods? (Enter your answer to three decimal places.)
