A box contains 1 red and 3 identical white balls. Two balls are drawn at random in succession without replacement. Write the sample space for this experiment.


Suppose red and white balls are denoted by R and W respectively. When two balls are drawn in succession without replacement then it could be first red and second white ball, then we denote this outcome by RW and so on.

The sample space is given by

S= {RW, WR, WW)
