Assume that a committee consists of 12 people including the chairperson and that the chairperson must select a committee of 3 people from the other 11 members of the committee. In how many ways can this be done?

There are 12 ways to pick a chairman, and then we have to choose 3 of the remaining 11 number of ways = 12*C(11,3) = 12(165) = 1980

i tried that already and its not the right answer :(..
