A photocopying machine produces, on average, 1 defective photocopy out of every 50 pages copied. a) What is the probability that, when photocopying a 40page article, the machine will produce no more that 2 defective pages? b) What is the probability that the eleventh photocopied page will be the first defective? c) How many pages do you expect to photocopy to produce the third defective page? d) You are to photocopy 5 books of 100 pages each. What is the probability that the photocopies of only 2 of the books will contain defective pages?
