Question 320901: if you make guesses for four multiple-choice test questions (each with five possible answers), what is the probability of getting at least one correct? If a very lenient instructor says that passing the test occurs if there is at least one correct answer can you reasonably expect to pass by guessing
Answer by toidayma(44) (Show Source): You can put this solution on YOUR website!
The probability of getting at least one correct guess = 1 - the probability of getting no guess correct.
The probability of getting one guess incorrect is : 4/5
The probability of getting for guesses incorrect is (4/5)^4
Therefore, the probability of passing the test is 1 - (4/5)^4. :-)
