Question 1200617: Really Big Medical Center (RBMC) is testing patients who have spent time in grassy areas this summer and fall for Lyme disease. Suppose that the probability of someone with exposure to tall grass having Lyme is .3 (or 30 percent). In a sample of 15 patients, what is the expected value (mean) of the number of patients with Lyme disease? Round your answer to 1 decimal place.
