Please select the best answer from the choices provided

Answer 1

The probability that a patient’s condition will not worsen after the procedure is 100% - 4% = 96%. Since the procedure is independent for each patient, the probability that none of the 5 patients’ conditions will worsen is 0.96^5 ≈ 81.5%. So, the best answer from the choices provided is 81.5%.
