Hi (this is not homework! I just find it easy to make mistakes on these and need to know for a simple estimate at work.)
Out of a set S of 10,000 items, 50 of them are special. I need to know how many ways I can select a set of 50 items from S that contains at least 2 special items.
I calculate this as: "50 choose 2" x "9,998 choose 48".
Is this correct? Thank you! E
