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?
