From a Group of 8 People, Including Timo and Gary, 3 people are to be selected at random to work on a certain project. What is the probability that 3 people selected will include Timo but not Gary	Choose one:
A) 5/56	B) 9/56	C) 15/56	D) 21/56	E) 25/56
Number of ways of selecting 3 people out of 8 people = 8C3   In the three members Timo will always be there in the team. At this step we have vacancy for 2 more members and 7 members are available. Gary cannot be there in the team. So 2 members have to be selected and the number of available members = 7 -Gary = 6   Number of ways to form a 3 member team that includes Timo and excludes Gary = 615/562   Probability = 615/562/815/563 = 15/56   Answer: 15/56
