Question
A box contains 1 red and 3 black balls. Two balls are drawn at random in succession without replacement. Write the sample space for this experiment.
Solution
The box contains one red ball and three black balls.
Let us denote the red ball as R and the three black balls as B1, B2 and B3.
The sample space of this experiment is given by
S = {(R, B1), (R, B2), (R, B3), (B1, R), (B1, B2), (B1, B3), (B2, B1), (B2, B3), (B2, R), (B3, R), (B3, B1), (B3, B2)}
