Question 762117: a teacher gave students eleven questions and wrote that she would randomly choose one of the eleven questions for an exam. If Harry prepared for only on questions what is the probability that he did not study for the question that the teacher put on the exam Answer by ramkikk66(644) (Show Source):
You can put this solution on YOUR website! Probability that the teacher gives the one question that Harry studied = 1/11
So probability that she gave one of the questions he did not study = 1 - 1/11 = 10/11.
