There are ten possible players for the VI to represent a tennis club and of these the captain and the secretary must be in the team. In how many ways can the team be selected?

there is 6 places as VI = 6

10 players (includes captain & secretary)

C S _ _ _ _

there is 4 spaces to fill thus

the amount of ways;

2 x 8C4 = 140

there are 140 ways

the text book states the answer is 70

Did I make a mistake by multiplying 8C4 by 2?
