The government of a large city wants to know if its citizens will support a three-year tax increase to provide additional support to the city's community college system. The government decides to conduct a survey of the city's residents before placing a tax increase initiative on the ballot. Which one of the following is most appropriate for obtaining a sample of the city's residents?
a. Survey a random sample of persons within each geographic region of the city.
b. Survey a random sample of community college professors living in the city.
c. Survey every tenth person who walks into the city's government center on two randomly selected days of the week.
d. Survey a random sample of persons within each geographic region of the state in which the city is located.

If I randomly select 15 students from the combined classes, in a way that the order of my selection does not matter, what is the probability that all 15 students can from Section A? b). If I randomly select 15 students from the combined classes, in a way that the order of my selection does not matter, what is the probability that all 15 students can from Section B? c).
