Must read! a multiple choice question on a test has 4 answer choices. you guess at the answer. what is the probability that you will select the correct choice. write your answer as a percent. would the answer be 25%?

Yep :) You're right!

The total probability of anything is always 100%, obviously.

If there are 4 choices, and you're equally likely to select either one, you can do 100% / 4 choices = 25%.

One of them have to be correct, so 1 of the 4 are bound to be right. 1/4 is also the same as 25%, hence you're correct! :)
