Twenty people are preparing to play basketball
using a five member team. How many different five person teams can be put together.
thank u so much, i really appreciate it..
We have respectively $\displaystyle 20\times 19\times 18 \times 17 \times 16 $*possibilities for 1st 2nd 3rd 4th and 5th player. But we don't care of order so $\displaystyle P = \frac{20\times 19\times 18 \times 17 \times 16}{5\times 4\times 3 \times 2 \times 1} $
