A bag contains four red marbles, two Yellow Marbles and five blue marbles.

Two marbles are drawn at random without replacement.

Total number of marbles are,

$4\text{ + 2 + 5 = 11}$

There are 11 ways to select first marble and 10 ways to select second marble.

The total number of possible outcomes are calculated as,

$Total\text{ number of outcomes = 11 }\times\text{ 10 = 110 }$

Thus the total number of possible outcomes are 110.
