    Since we already know that there is a 25% chance to guess the correct answer to a multiple choice question, all we have to do is multiply .25 and 68 to get the expected amount of answers a student can possibly guess. We multiply .25 since it is the decimal form of 25% and 68 is our total questions.

    .25 x 68 = 17

    Therefore, a student can expect to guess 17 answers correct on a test with 68 multiple choice questions.
