Question from susan: Out of 80 numbers how many combinations of 8 are there and what are they. |
Hi Susan,
The number of combinations of $k$ things taken from $n$ things is called $n$ choose $k.$ You can find a definition and an example in a response to an earlier question. Google will do the arithmetic for you. If you type 80 choose 8 into the Google search window you get the response 28,987,537,150. Way too many to list.
