Answer:
Option C.
Explanation:
It is given that a box contains red, blue, green, purple, and yellow crayons such that the probability of drawing a purple crayon is 3/7.
We draw two crayons randomly such that both draws are independent.
Let X be a random variable that assigns the number of purple crayons to each outcome.
We need to find the range of X.
If no purple crayon is selected, then X=0
If 1 purple crayon is selected, then X=1
If 2 purple crayons are selected, then X=2
The range of X is {0,1,2}.
Therefore, the correct option is C.
