Answered by admin @ 13/08/2021

Given that there are 3 multiple choice questions and each question has 4 choices.

= 4^3

= 64.

Number of Ways of getting all the correct answers = 1^3 = 1.

Number of ways of getting all the incorrect answers = 64 - 1

= 63.

Thus the probability that the student can fail to get all answer correct is 63.

Hope this helps!
