Twenty-eight percent of college students say they use credit cards because of the rewards program.  You randomly select 10 college students and ask each to name the reason he or she uses credit cards.  To three significant digits, find the probability that the number of college students who say they use credit cards because of the rewards program is:

1. exactly two.
   {#1}
   
   
2. more than two.
   {#2}
   
   
3. between two and five inclusive.
