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

on the interval 0 ≤ x ≤ 7, for maximum value, f'(x) = 0.
Answer:
Step-by-step explanation:
To solve this proportion, we will divide the two given denominators.
Now, we have: 30 ÷ 5 = 6
Next, we will multiply the given numerator by the quotient: 3 × 6 = 18
So, our final proportion will have to be:
