According to the chart, 11 out of 75 designers preferred yellow, so 64 out of 75 designers did not prefer yellow. Therefore, the probability that a designer does not prefer yellow is 64/75, which simplifies to 0.853. However, none of the answer choices match exactly, so the closest option is C, which has a probability of 0.885 (i.e. 1 - probability of preferring yellow).
