You can put this solution on YOUR website! I have two probability questions.
1) from 8 shirts, 6 pair. of slacks, and 4 jackets how many different outfits can be made?
8*6*4 = 192 outfits
-------------------------------
2) 9 points are placed on a circle, how many triangles can be formed using these points, three at a time as vertices?
Every set of three points can determine a trianble because
no set of three points are on the same line.
Ans: 9C3 = (9*8*7)/(1*2*3) = 84
