Purchasing magazine reported the results of a survey in which buyers were asked a
series of questions with regard to internet usage. One question asked was how they
would use the internet if security and other issues could be resolved. Seventy-eight
percent said they would use it for pricing information, 75% said they would use it
to send purchase orders, and 70% said they would use it for purchase order
acknowledgments. Assume that these percentages hold true for all buyers. A
researcher randomly samples 20 buyers and asked them how they would use the
internet if security and other issues could be resolved. What is the probability that
fewer than 12 would use the internet for purchase orders acknowledgments?
