Question

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.

Answer 1

Red ball = 1

White balls = 3

Two balls are drawn at random in succession without replacement

let the red ball be R

let the white ball be W

Sample space = {RW, WW, WR}

Answer: Sample space = {RW, WW, WR}

Answer 2

here is your answer OK


It is given that the box contains one white ball and three identical black balls.
Let us denote the white ball with W and a black ball with B.
When two balls are drawn at random in succession without replacement, the sample space for this experiment will be given by
S = {WB, BW, BB}
