A student is taking a multiple-choice exam in which each question has four choices. Assuming that she has no knowledge of the correct answers to any of the questions, she has decided on a strategy in which she will place four balls (marked A, B, C, and D) into a box. She randomly selects one ball for each question and replaces the ball in the box. The marking on the ball will determine her answer to the question. There are...

A student needs to buy 6 books this semester. The number of books that she will be able to find used is a binomial random variable with n-6 and p 0.30. In other words, the probability that she will find any given book used is 0.30. Assuming that all events are independent, what is the probability that she will find exactly 2 used books? Round your final answer to three decimal places
