Question

anyone solve this............

Answer 1

the total probability of selecting 2 balls from the 11 balls is = 11c2 = 11*5
probability of selecting balls being different colors = 5c1*6c1 = 5*6
hence required probability
= ( different color /total outcome )
= 30/55
= 6/11
hence option (2) 6/11 is correct
