39!C5! trying to calculate the combinations

39!C5!  picking 5 numbers from 1-39   please help!

$$\small{\text{ $ \left(\begin{array}{c} 39 \\ 5 \end{array}\right) $ }}\\\\ \small{\text{ $ \begin{array}{ccc} &=&\dfrac{39!}{5!\cdot (39-5)! }\\\\ &=&\dfrac{39!}{5!\cdot 34! }\\\\ &=&\dfrac{\not{34!}\cdot 35 \cdot 36 \cdot 37 \cdot 38 \cdot 39}{5!\cdot \not{34!} }\\\\ &=&\dfrac{35 \cdot 36 \cdot 37 \cdot 38 \cdot 39}{2\cdot 3 \cdot 4 \cdot 5}\\\\ &=&\dfrac{35}{5}\cdot \dfrac{36}{4}\cdot 37 \cdot \dfrac{38}{2} \cdot \dfrac{39}{3}\\\\ &=&7\cdot 9 \cdot 37 \cdot 19 \cdot 13\\\\ &=&575757 \end{array} $ }}$$

The number of combinations you can make from 39 numbers taken 5 at a time, is 575757.

I don't believe that you meant to use the factorial signs.

This is just given by C(39,5)   = 575,757  ways of picking 5 numbers from 39

Yes there are 39C5 different combinations that could be chosen

on the web2 calc you can enter it like this

nCr(39,5)
