Question

Five chess players take part in a tournament. Every player plays once with each of his/her opponents. How many games are play?

Answer 1

There is a total of 10 games played.

How many games are played?

There are 5 players, If we select a given player, then that player will play one game with each of the other 4 players.

So we have 4 games at the moment.

Now we select one of the other 4 players, (we don't count the one we choose before). The one that we choose now will play one game wich each one of the remaining 3, so we add 3 more games.

Now we do the same with the remaining 3, this time we add 2 more games.

Now we do that with the remaining 2, now we add 1 more game.

Adding all the games we have:

4 + 3 + 2 + 1 = 10

There is a total of 10 games played.
