Given : Two balls are selected at random with replacement from a bag containing 3 red, 3 black and 2 green balls.
To Find : the possible outcomes are:
Solution:
3 Red Ball
3 Black Ball
2 Green Ball
Total Balls = 3 + 3 + 2 = 8
if Balls are not identical
1st ball can be selected in 8 ways
2nd ball is selected after replacement
hence 2nd ball can be selected in 8 ways
Total ways = 8 * 8 = 64
if Balls are identical
1st ball can be selected in 3 ways ( Red , Black or Blue)
2nd ball is selected after replacement
hence 2nd ball can be selected in 3 ways
Total ways = 3 * 3 = 9
