<span>Total sample space = 20C2 = 190
The number of ways of selecting 2 balls of same color from a suit of 15 red balls
15C2 = 105
The number of ways of selecting 2 balls of same color from a suit of 5 blue balls
5C2 = 10
Thus the probability that the person picks 2 balls of same color = [105/190 + 10/190]
= 115/190 = 23/38</span>
