Answer : There are 5 black and 6 red balls. So,
The number of ways of selecting 2 black balls from 5 black balls is 5C2, and number of ways of selecting 3 red balls from 6 red balls is 6C3.
Thus using the multiplication principle, the total number of ways will be
5C2 × 6C3 ways.
⇒200 ways
Thus, the total number of ways in which 2 black and 3 red balls can be selected is 200.
