The probability that the student does not know the answer but he randomly guesses it is 0.146025
<h3>How to solve for the probability of having a correct guess</h3>The question has only one right answer out of 5 choices.
Probability he answers incorrectly:
1 - 0.55 * 4/5
= 0.45 * 0.8
= 0.36
Probability he does not know answer but answers the question correctly
= 0.09/0.55+0.09
= 0.140625
