A basketball coach will select the members of a five-player team from among 9 players, including John and Peter. If the five players are chosen at random, what is the probability that the coach chooses a team that includes both John and Peter?

If john and peter are included,the probability for both is 1.

So we need to choose 3 players from 7 players.

1*1*7C3=35

5 players can be chosen from 9 players=9C5=126

35/126=5/18
