Question

you draw two marbles without replacement from a bag containing four red marbles, two Yellow Marbles and five blue marbles, find the number of possible outcomes

Answer 1

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 }*\text{ 10 = 110 }`

Thus the total number of possible outcomes are 110.
