Answer:
0.140625
Step-by-step explanation:
Given that multiple-choice questions each have four possible answers (a comma b comma c comma d ), one of which is correct. Assume that you guess the answers to three such questions.
Each question is independent of the other with constant probability
p = Prob for correct guess = 1/4 = 0.25
q = prob for wrong guess = 1-p = 0.75
Hence
, since each question is independent of the other
=
12.5, 20, 22.5, 32 is the way from least to greatest. Hope this helps.
Well, let's multiply them!
8/3 * 9/7 = 72/21
8/3 x 9/4 = 72/12.
We know the one with the smallest denominator is larger if the numerator is the same. So that means
72/12 is larger.
Yes your answer is correct
