Question

Quizplus · Accepted Answer

The probability of success in each trial is 0.3. The probability of failure is 1-0.3=0.7. The clinical trials are conducted independently of each other. The probability that all trials are not successful is the product of the probabilities of each trial being not successful. Therefore, the probability that the clinical trials are not successful is (0.7)^5 = 0.16807. Therefore, the probability that the clinical trials are successful is 1-0.16807 = 0.83193. Therefore, the best choice is D.
