Question 211655
I'm stuck on this one does anyone have the solution 
Two balls are to be selected without replacement from a bag containing on red, one blue, one green, and one yellow ball. How many points are there in the sample space?
--------------------------------------
There are 4 balls.
The number of pairs of balls is 4C2 = 6
------------
Each point can be arranged in two orders.
---
Total number of points is 2*6 = 12
