Dr. Jordan, a dermatologist, is creating a face wash for her patients with severe skin allergies. However, the product is not yet ready to be released to the public. Tests indicate 16% of people with "highly sensitive skin" who sampled the facial wash still exhibit an allergic reaction. Assume the test results are representative of the general population. If Dr. Jordan released the face wash to the public now, and 86 people with "highly sensitive skin" used it, what is the probability that exactly 18 will have an allergic reaction?
