Given : A bucket contains 2 red balls, 4 blue balls, and 6 white balls.
Two balls are drawn at random.
To Find : probability that either both are blue or both are non-blue.
Solution:
2 red balls, 4 blue balls, and 6 white balls.
Total Balls = 2 + 4 + 6 = 12
Blue Balls = 4
Non Blue Balls = 12 - 4 = 8
2 balls out of 12 can be selected in ¹²C₂ = 66 ways
both are blue => ⁴C₂ = 6
both are non blue => ⁸C₂ = 28 Ways
probability that either both are blue or both are non-blue = (6 + 28)/66
= 34/66
= 17/33
