There are 16 students who choose up sides to play soccer. How many different teams of 8 can be formed?
Pretty sure it's \[\left(\begin{matrix}16 \\ 8\end{matrix}\right)\] This is because order is not important. The same team could be made by choosing students in a different order.
answers right here
12870 120 40320 720
12870. But do you understand why?
no not really
Have you learned combinations? Like:
yea i learned them silly
haha ok.So what part is tripping you up?
Just approaching the question?
i think lol i dunno
Well one way people refer to combinations is like "16 choose 8". And sometimes it's written as 16C8. So 16 students for a team of 8: "16 choose 8". Just remember that in this situation order is not important. Unlike the question you had earlier where you needed to find the number of possible words.
this lesson we are learning in class the teacher is not exsplaining it in depth enough for us to understand most of the students got a 30% on the 1st test cause we didn't know anything he threw at us so yea its hard for me to understand it
That's unfortunate. But good for you for coming here and taking taking ownership of your education.
