Fourteen percent of workers believe they will need less than $250,000 when they retire.  You randomly select 10 workers and ask each how much money he or she thinks they will need for retirement.  To three significant digits, find the probability that the number of workers who say they will need less than $250,000 when they retire is:

1. exactly two.
   {#1}
   
   
2. more than six.
   {#2}
   
   
3. at most five.
