Question 1168663: On a 7 question multiple-choice test, where each question has 2 answers, what would be the probability of getting at least one question wrong Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! What is the probability of getting no problems wrong? That is (1/2)^7=1/128.
All the remaining possibilities are probability of getting at least 1 wrong or 127/128, the complement.
