Question 1022083
there are 11 people in an office with 3 different phone lines.
If all the lines begin to ring at once, how many groups of 3 
people can answer these lines?
<pre>
Choose the person to answer the first phone in 11 ways.
That leaves 10 people to choose to answer the second phone.
That leaves 9 people to choose to answer the third phone.

Answer 11*10*9 = 11P3 = 990 ways
