Answer :

Let R be the event a red ball is drawn and W be the event a white ball is drawn

Since all the white balls are identical so the event of drawing any one of the three-white ball is same.

Total Number of Sample space =(2^{2}-1)=3 (Since both the balls cannot be red)

We define the possible outcomes by an ordered set (x, y)

x denotes drawing the first ball

y denotes drawing the second ball

Sample space S={(W,W),(W,R),(R,W)}
