There are 5 multiple choice questions with 4 posiible answers each out of which only one is correct.What is the probability of getting atleast 3 answers

Total no of questions=5
Possible answers=20 (5×4)
Total correct answers=5 (as there is only one ans correct in each ques)
So the probability of getting at least 3 ans correct will be= 3/20
: )

No. of MCQ questions = 5 No. of correct answer in 1 MCQ question = 1 out of 4 options No. of possible answers total = 5 * 4 = 20 No. of total correct answers = 5/20 Probability of getting 3 answers correct is 3/20
