Expert Answer
Total number of balls in the bag = 12
Number of balls of each colour = 12/4 = 3
probability of selecting a ball of yellow colour = probability of selecting a ball of blue colour = 3/12 = 1/4
probability of selecting a ball of green colour = probability of selecting a ball of red colour = 3/12 = 1/4
