Question

Suppose there is a 5 questions multiple choice quiz. Each question has 4 answers (A, B, C, and C). If you strictly guessing, find the probability that you get 3 correct?

Answer 1

1/1024

Explanation:

favourable outcome / possible outcomes = x / 4x4x4x4x4

= x/ 1024

Since we only need to get 3 correct:

= 1x1x1 / 1024

= 1 / 1024

The probability of getting 3/5 questions correct, with only guessing is 1/1024
