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 probability that at least two experience side effects?
- A. 0.8687
- B. 0.1313
- C. 0.00847
- D. 0.0003
Correct Answer: C
Rationale: The probability of at least two experiencing side effects is P(X≥2) = 1 - [P(X=0) + P(X=1)]. Using binomial calculations: P(X=0) = 0.8687, P(X=1) = (5 choose 1) * 0.03 * 0.97^4 = 0.1342, so P(X≥2) = 1 - (0.8687 + 0.1342) = 0.00847, matching the document.
