A bag contains six marbles: two red, two blue, and two green. If two marbles are drawn at random, what is the probability that they are the same color?
Is the below approach correct
No of ways of choosing 2 balls of the same colour is to choose one of the 3 sets = 3 ways
Total ways of choosing 2 balls is 6c2 = 15 ways
probability of choosing 2 of the same colour is 3/15 => 1/5.
