A poll is given, showing 45% are in favor of a new building project. If 7 people are chosen at random, what is the probability that exactly 3 of them favor the new building project? Type your answer as a decimal. Be sure to use the appropriate rounding rule. (Hint: Use Stat Crunch)   A manufacturing machine has a 10% defect rate.
