Given:

A bag containing four red marbles, two yellow marbles, and five blue marbles

Find:

No.of ways to choose two balls from from a bag containing four red marbles, two yellow marbles, and five blue marbles

Solution:

Let us assume all the balls are distinct

Total no. of balls =4+2+5

                              =11

NO. of ways to draw two balls=¹¹C₂

                                                     =55

Therefore, total no. of ways drawing two basll from 11 balss =11
