During the break of a football match, the coach will make 3 substitutions. If the team consists of 12 players among which there are 2 forwards, what is the probability that none of the forwards will be substituted?	Answers:
A) 21/55	B) 18/44	C) 28/55	D) 28/44	E) 36/55
Required probability = no. of favorable outcome/ total no. of outcomes   out of 12 players any 3 can be selected in 12C3 ways   after removing 2 forwards any 3 players can be selected from the remaining 9 players in 9C3 ways   thus required probability = 9C3/12C3 =21/55=21/55
