When an opinion poll calls landline telephone numbers at random, approximately 30% of the numbers are working residential phone numbers. The remainder are either non-residential, non-working, or computer/fax numbers. You watch the random dialing machine make 20 calls. Round all answers to four decimal places.
Blank #1: What is the probability that exactly three calls reach working residential numbers?
Blank #2: What is the probability that at most three calls reach working residential numbers?
Blank #3: What is the probability that at least three calls reach working residential numbers?
Blank #4: What is the probability that fewer than three calls reach working residential numbers?
Blank #5: What is the probability that more than three calls reach working residential numbers?
