# A bag conta

Given that we need to draw 2 black and 3 red balls from a bag of 5 black and 6 red balls.

Let us assume the no. of ways of drawing be N.

N = (no. of ways of selecting 2 black balls from 5 black balls) × (no. of ways of selecting 3 red balls from 6 red balls)

N = (5C2) × (6C3)

We know that ,

And also n! = (n)(n – 1)......2.1

N = 10 × 20

N = 200

The no. of ways of drawing 2 black and 3 red balls is 200.
