another question? In how many ways can a two person social committie be chosen from a club of 12 members?
my solu tion is 2 C 12..i have 2!/-10*12! im lost with this one can you have a negative number in the problem……didnt know how to carry on with this problem….or am i wrong it should be a permatation?
you have to interchange the two… it is 12C2 not 2C12…
you have 12 people. you need to choose any two from those 12… hence 12C2…
