Counting Methods A company has 12 male and 10 female employees, and needs to nominate 3 men and 3 women for the company bowling team.
How many different teams can be formed?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Answer. C%5B12%5D%5E3.C%5B10%5D%5E3 = 220*120 different teams can be formed.

Solution

You can choose 3 men of 12 by C%5B12%5D%5E3 ways = %2812%2A11%2A10%29%2F%281%2A2%2A3%29 = 2*11*10 = 220 ways.

You can choose 3 women of 10 by C%5B10%5D%5E3 ways = %2810%2A9%2A8%29%2F%281%2A2%2A3%29 = 10*3*4 = 120 ways.

You can then combine men and women by 220*120 ways.
