Answer:

1/6

Step-by-step explanation:

Number of orange crayons = 2

Total number of crayons = 2 + 4 + 1 + 2 + 3 = 12

Probability is calculated as:

\frac{\text{Number of Favorable outcomes}}{\text{Total number of outcomes}}

Here the favorable or desired outcome is picking up an orange crayon. So number of favorable outcomes will be 2 as 2 orange crayons are available.

Total number of outcomes is 12 which is the sum of all the crayons available.

So, the probability the crayon she pulls out will be orange = \frac{2}{12}=\frac{1}{6}
