Probability of passing a test?

No response

A student went to do an exam which had 100 questions, where each question had 4 answers to choose from and only one of the 4 answers is correct. Calculate the probability of the student passing the exam if he has to get at least 50 answers right if the student randomly answered all the 100 questions.
