Dave fails quizzes with probability 1/4, independent of other quizzes. (a) what is the probability that dave fails exactly two of the next six quizzes? (b) what is the expected number of quizzes that dave will pass before he has failed three times? (c) what is the probability that the second and third time dave fails a quiz will occur when he takes his eighth and ninth quizzes, respectively? (d) what is the probability that dave fails two quizzes in a row before he passes two quizzes in a row?

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.
