Question

A box contains one red and three white balls. two balls are drawn at random in succession without replacement. then write the sample space for this experiment

Answer 1

Given a box containing 1 red and 3 identical white balls.

∴∴ Let them denote as R,W,W,W

Since the white balls are identical drawing either white balls will be same.

∴∴ The sample space S={RW,WW,WR}
