which leads us to

which uses the compliment of
to find the probability of getting at least 2 questions correct.
Note that since
and
are mutually exclusive, we have

Then
as we have
to answer the questions incorrectly divided by the total
to answer the questions.
Exactly 1 answer correct: 
Therefore
