According to a July 31, 2013, posting on cnn.com subsequent to the death of a child who bit into a peanut, a 2010 study in the journal Pediatrics found that 8% of children younger than 18 in the United States have at least one food allergy. Among those with food allergies, about 39% 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?

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?

Show me a vann diagram and all the necessary steps and details from scratch as much as possible please. Thank you
