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. ;-)
