Question 23253: I need help with this problem:


From a box of 10 light bulbs, 4 are to be removed. How many different sets
of 4 bulbs could be removed?


I am guessing that if 4 are to be removed from the 10 light bulbs, then 6 will be remaining, 6!; I am stumped on the next step, can you help me?

You can put this solution on YOUR website!
This is a "combination" problem. You are choosing
sets of bulbs. You are not arranging the bulbs.
The answer is 10C4 = 10!/[6!*4!] = 210
