An executive committee of three is selected from a group of ten. Which expression best describes the number of combinations?
These are my choices. I have to have one of these as the answer. I am stuck.
My answer was B. 10!, but I am still not sure. Can anyone help me please?
A. 10P3 (small 10 and 3)
C. 3P10 (small 3 and 10)
D. 10P3/3! (small 10 and 3 on top, big 3! on the bottom)
