At the first meeting of Manchester backgammon club the members decided to have a tournament to determine who their best players were. Each member played one game with every other member. How many games were played altogether if there are ten members in the club???

I agree with your answers to the first 4 questions.
for the last:
Each of the 10 players plays against the other 9.
So that is 90
But...
it includes A vs B and B vs A, which is the same game, so we divide the above by 2
so there are 45 games.
Or ... shortcut way
choose pairs of 2's from 10
= C(10,2) = 45
