A pharmaceutical lab states that a drug causes negative side effects in 3 of every 100 patients. To confirm this affirmation, another laboratory chooses 5 people at random who have consumed the drug. What is the average number of patients that the laboratory should expect to experience side effects if they choose 100 patients at random?
- A. 1
- B. 2
- C. 3
- D. 4
Correct Answer: C
Rationale: The expected value (mean) of a binomial distribution is n * p. Here, n=100 and p=0.03, so U = 100 * 0.03 = 3, as calculated in the document.
