Alright, let's break it down into an equation.1 question has 4 choices.Assuming that only one is right that would give you a 25% chance of being correct if you randomly chose an answer.If 2 of the answers are the same, and are both the correct answer, then 2/4 of the choices are correct. So picking an answer at random would leave you with a 50% chance of correctly answering the question.Simple.

In that case, there's only one option that reads '50% chance.' You have only one chance of drawing it (out of four), thus, you have a 25% chance to answer correctly.
