Work Step by Step
There are $7$ pieces of paper, and $2$ are taken at a time.
So the sample space would be :
[1 and 2, 1 and 3, 1 and 4, 1 and 5, 1 and 6, 1 and 7, 2 and 3, 2 and 4, 2 and 5, 2 and 6, 2 and 7, 3 and 4, 3 and 5, 3 and 6, 3 and 7, 4 and 5, 4 and 6, 4 and 7, 5 and 6, 5 and 7, 6 and 7]
As these are the possible combinations at which the papers could be pulled out.
