You are in charge of tournament playoffs for bantam, midget, and
juvenile hockey. Only the winning team will advance to the next round
(single-elimination format). The higher ranking team(s) get a bye if there are not
enough teams to complete a round. There are 9 bantam teams, 8 midget, and 5 juvenile
hockey teams making the playoffs. How many rounds are needed for each
tournament? (Hint: Draw a diagram to show each round for each set of
playoffs.) Use the Playoff Scheduler to check your work.
