In a tournament there are sixteen players  $S_1,S_2\mathrm{........}{S}_{16}$  and divided into eight pairs at random from each game a winner is decided on the basis of a game played between the two players of the pair. Assuming that  all the players have equal strength

	Column-I		Column-II
A)	The probability that  $S_1$ is one of the winner	p)	$\frac{8}{15}$
B)	The probability that exactly one of  $S_1$  or $S_2$  is a winner	q)	$\frac{1}{2}$
C)	Both $S_1$ and  $S_2$ are among eight winners	r)	$\frac{7}{30}$
D)	Both $S_1$ and  $S_2$ are not among eight winners	s)	$\frac{1}{240}$
