Question 188714: Attached is a probability question with two parts. I feel I have question A figured out. However question B I cannot figure out and cannot figure out a solution. Could someone please help me with these two questions and include a formula with steps. Thanks in advance. The question is:
A drug used to reduce high blood pressure produces side effects in 4% of the patients. Three patients who have taken the drug are selected at random. What is the probability that:
A. they all had side effects.
B. none of them had side effects
The answer I came up with for A is: .000064
Any help is greatly appreciated. Thanks again. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! A drug used to reduce high blood pressure produces side effects in 4% of the patients. Three patients who have taken the drug are selected at random. What is the probability that:
A. they all had side effects.
Ans: 0.04^3 = 0.000064

B. none of them had side effects
Ans: (1-0.04)^3 = 0.96^3 = 0.8847
