## comput313 Group Title How many combinations are possible if a committee of 3 is chosen from a group of 25 people? 2 years ago 2 years ago

obviously 25c3. Because we are choosing 3 from 25.

There is a total of 2,300 combinations.

$$\Large \color{Black}{\Rightarrow 25c3 = {25! \over (25 - 3)! \times 3!} }$$

Looks like someone just answered it.

Remember - this is a combination problem, so you want to do 25 C 3. When you do that, you are finding out the total number of combinations that you could possibly have. Also, remember that combinations can repeat.

You're very welcome! =)

Sorry - @ParthKohli - I'm not sure what you mean?

Maybe the moderators will tell you about it

Did I do something wrong?

Did I do something wrong? What do the moderators need to tell me about - I'm confused.

@LyraElizabethAdams It's probably that you should show the steps or help them get the answer rather than just blurt it out.
