Step-by-step explanation:
As all the questions of the exam carry 2 points, at least
questions need to be correct to get 56 marks.
In order to get a maximum of 56 marks, at most 28 answers needs to be correct.
Every question has two option. Hence, the probability of getting a particular question right is
.
The probability that exactly n questions will be right is
.
The probability that at most 28 questions will be right is ∑
