A bag contains 4 balls of different colours red, green, blue and yellow.A person draws two balls from the bag, one after the another without replacement.Describe the sample space for the experiment.

Hello student,

Let the balls of red, green, blue and yellow colours be denoted by R, G, B and Y. If the first ball drawn is R then the secondball drawn may be G, B or Y. Similarly, if the first ball drawn is G then thesecondball drawn may be R, B or Y and so on.
Sample space, S = { (R,G), (R,B), (R,Y), (G,R), (G,Y), (G,B), (B,R), (B,Y), (B,G),(Y,R), (Y,B), (Y,G) }.

Thanks and Regards
