A telemarketer has 12 people on his contact list. Suppose he will randomly select 8 people to call during the next shift.
a. How many different calling schedules are possible?
b. Suppose only 2 of the 12 will definitely purchase the product when contacted. What is the probability that these 2 people will be the first 2 called?
c. Suppose another 2 of the 12 will ask to be placed on the do-not-call list when contacted. What is the probability that these 2 people will not be called?
