Find experimental probability of not getting yellow

The probability of not getting yellow is 2/3 ⇒ 3rd answer

Step-by-step explanation:

* Lets describe the meaning of experimental probability

- Experimental probability is the ratio of the number of times an

  event occurs to the total number of trials

∵ There are 6 blue marbles , 4 yellow marble and 2 red marbles

∴ the total number of marbles = 6 + 4 + 2 = 12 marbles

- The probability of each color is the number of the marbles have the

 same color divided by the total number of the marbles

∴ The probability of blue marbles = 6/12 = 1/2

∴ The probability of yellow marbles = 4/12 = 1/3

∴ The probability of red marbles = 2/12 = 1/6

- To find the probability of not yellow you can add the probability of

  blue and red OR subtract the probability of yellow from 1 because

  the total of probability of all colors is 1

∴ The probability of not yellow = 6/12 + 2/12 = 8/12 = 2/3

OR

∴ The probability of not yellow = 1 - 4/12 = 12/12 - 4/12 = 8/12 = 2/3

* The probability of not getting yellow is 2/3

The correct answer is  3rd option

The probability of getting not yellow = 2/3

Step-by-step explanation:

It is given that, there are 6 blue marbles, 4 yellow marbles and 2 red marbles

To find the probability

Total number of marbles = 12 marbles

number of yellow marbles = 4 marbles

probability of getting yellow = 4/12 = 1/3

probability of getting not yellow = 1 - 1/3 = 2/3

Therefore the correct answer is 3rd option
