##### 1 Answer

#### Answer:

C

#### Explanation:

I'm going to answer assuming that the probability of picking the red, blue, yellow, and purple cards are all equal (the word is missing in the question but I think we can infer that it was meant to be "equal").

We'd expect the results of picking the cards to all be equal over 100 draws, and so there should be 25 red, blue, yellow, and purple draws.

The actual results has red at 33.

Therefore C, Shelly's results are higher than predicted.
