It is given that the box contains 1 red ball and 3 identical white balls. Let us denote the red ball with R and a white ball with W.
When two balls are drawn at random in succession without replacement, the sample space is given by S = {RW, WR, WW}

Let R stands for red ball and W stands for white ball. Then required sample space = S
= {RW, WR, WW}
= {R,W),(W,R),(W,W)}
