Explanation

There are 400 opinions. 46/400 prefer yellow. So 1 - 46/400 = 177/200 = 0.885 does not prefer yellow.

To calculate the probability that a designer does not prefer yellow, we need to consider the total number of opinions and the number of opinions that are not in favor of yellow.

According to the data provided, the total number of opinions is the sum of the opinions for each color:

Total opinions = 92 (red) + 86 (orange) + 46 (yellow) + 91 (green) + 37 (blue) + 46 (indigo) + 2 (violet) = 400

Now, let's calculate the number of opinions that are not in favor of yellow. This includes all the opinions for colors other than yellow:

Opinions not in favor of yellow = 92 (red) + 86 (orange) + 91 (green) + 37 (blue) + 46 (indigo) + 2 (violet) = 354

To calculate the probability, we divide the number of opinions not in favor of yellow by the total number of opinions:

Probability = Opinions not in favor of yellow / Total opinions = 354 / 400 = 0.885

Therefore, the probability that a designer does not prefer yellow is 0.885.

The correct answer is B. 0.885.
