Question

Joe hasn't studied for the Pass/Fail final test in his statistics class, but he does have some background, so he's pretty sure he can get or guess the right answer about 60% of the time. Assuming there are 100 multiple choice questions, and the lowest passing score is 60%, what is the probability Joe will pass the test?

Answer 1

The probability that Joe will pass the test is 100%.

How to calculate the probability

From the information, Joe hasn't studied for the final test in his statistics class, but he does have some background, so he's sure he can get the right answer about 60% of the time.

Therefore, if there are 100 multiple choice questions, and the lowest passing score is 60%, the probability that Joe will pass is 100%. This is because he usually has a 60% passing rate and this tallies with the lowest percentage needed to pass.
