(a) which color was chosen by approximately one - third of the customers?
(b) approximately what percentage of the customers chose other or white? write your answer as a multiple of 10% - that is, 10%, 20%, 30%,...
(c) if 15% of the customers chose grey, approximately what percentage chose other?
options for (c): 2%, 5%, 33%, 45%

Explanation:

Step1: Analyze part (a)

One - third of customers. If we assume the total is 100%, one - third of 100% is approximately 33%. Looking at the pie - chart, the color closest to 33% is Black.

Step2: Analyze part (b)

We need to estimate the percentage of customers who chose Other or White. By visually inspecting the pie - chart, White and Other together seem to be around 20%.

Step3: Analyze part (c)

If 15% of customers chose Grey, and we want to find the percentage of customers who chose Other. Let's assume the total percentage is 100%. From visual inspection of the pie - chart, Other is around 5%.

Answer:

(a) Black
(b) 20%
(c) 5%
