Question 1120236: Probability. You blindly guessed the last five multiple-choice items of
an UPCAT practice test. What is the probability that you will
answer all five questions correctly? Please help. And please explain. Thankyou. Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! The number of options for each question is not known.
If T-F, or 2, it is (1/2)^5
if multiple choice with x choices, it is (1/x)^5, so 4 choices would be (1/4)^5 probability.
With 5 choices,it would be (1/5)^5.
