In how many ways can a commitee of 4 people be drawn from a group of 13 people? Solution In the first position, 13 people are possible to be chosen. Then, in the second position, only 12 are available because one of them has already been chosen for the first spot. For the third position, 11 people are available, and in the last position, only 10 are available. Therefore, 13 x 12 x 11 x 10 = 17,160 possibilities.
