Discussion Overview

The discussion revolves around calculating the total number of handshakes that occur during a football game between two teams, each consisting of eleven players. The scope includes mathematical reasoning and assumptions about the nature of the handshakes, particularly whether players shake hands only with members of the opposing team or also with their own teammates.

Discussion Character

  • Mathematical reasoning
  • Debate/contested

Main Points Raised

  • One participant states that if players only shake hands with members of the opposing team, the total number of handshakes would be 33^2, resulting in 1089 handshakes.
  • Another participant questions the significance of sub-teams and whether players shake hands within their own team, suggesting that the problem lacks clarity on this aspect.
  • A different participant proposes that if players shake hands with everyone except their own subteam, the total would be 1815 handshakes.
  • It is also suggested that if players shake hands with everyone else, including their own teammates, the total would be 2145 handshakes.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the conditions under which handshakes occur, leading to multiple competing views regarding the total number of handshakes.

Contextual Notes

The discussion highlights the ambiguity in the problem statement regarding the rules of handshaking, particularly concerning interactions between sub-teams and the opposing team.

Two football teams, both with an offense, defense and special team of eleven players each, exchange handshakes exhaustively between themselves. How many handshakes are applied overall?

Do the team members only shake hands with members of the other team? Or do the "sub-teams" (offensive/defensive/special) teams on the same team also shake hands? And do people on the same, say, offensive team shake hands with each other? I guess I'm puzzled as to why it matters that there are sub-teams unless there's some significance to them, but it seems not to specify any significance in the problem as stated?

They spank their own teammates.:wink:

I included sub-teams to explain the total overall number on a team (33).

I am reminded of youth leagues where it seems every player on one team is required to shake hands with every player on the other team.

I failed to explain specifically that the sport in question is American football.
 
Ok, so each person ONLY shakes hands with people that are members of the other team, and NOT with people on their own team.

In that case, there should be 33^2 (1089) handshakes.

If they each shake hands with everyone EXCEPT people from their own subteam, then 1815 handshakes total.

And if they each shake hands with everyone else, then 2145 handshakes.
