Default probability?

multiple choice questions each have five possible answers (a, b,c,d,e), one of which is correct. assume that you guess the answers to three such questions.use the multiplication rule to find the probability that the first two guesses are wrong and the third is correct. That is, find p(wwc), where c denotes a correct answer and w denotes a wrong answer?
