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

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

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.

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

OH, I see! Okay  sorry! I thought that since I put the explanation beneath the answer, that was pretty much the same. I'll remember that next time. Thanks! :)
