3. ADDITIONAL PRACTICE PROBLEMS
Seven people are going to a party: Alice, Bob, Carl, Diane, Eve, Frank, and George. When they have all arrived, everyone shakes hands.
Q1: How many handshakes were there altogether?
They then go to the table to eat, but they can't agree on a seating arrangement.
Q2: How many possibilities are there if Alice always stays at the head (since it is her birthday)?
Q3: How many possibilities are there if Alice can sit anywhere?
They decide to play bridge after dinner. When the cards have been dealt, Carl says that he thinks he got the same hand as last time.
Q4: What is the likelihood that he is right?
Finally, they decide to play chess. Alice just wants to watch, and sets up three boards.
Q5: How many different ways can they be matched?[/i]
