Hello, sarahlynn!

Assume you are given a test in which you are asked to match the 5 correct answers in the right column
with the 5 questions in the left column. .You can use each answer only once. .If you guess at each
question, what is the probability that you get all of them correct?

There are \(\displaystyle 5! = 120 \) possible orders to the answers you give.

There is only one correct order.

Therefore, the probability is \(\displaystyle \dfrac{1}{120}.\)
