    How to understand...

    Hi all,

    Please help me to understand the bellow sentence!

    "Each time the students have a 1 in 5 chance of guessing correctly."

    What does 'a 1 in 5 change' mean?

    Thanks a lot!

    This means that there probably are 5 answers (eg. in a multiple choice test), and only one is correct. So if you pick an anwser haphazardly, you will have a 1 in 5 chance to be correct.

    If there are 5 possible answers, then a student can guess and has a 20% chance of getting the correct answer. This is important because it caffects the accuracy of a test.
