1. According to the National Institute of Allergy and Infectious Diseases, approximately 7% of American children 4 years of age or under have a food allergy. A day care has capacity for 8 children in that age range. Assume that the children attending the daycare are independent. Let the random variableXbe the number of children in this day care who have a food allergy.

The probability that at least one of the eight children has a food allergy is
