The result of the sample question is biased, the sample is a random.

Explanation of Solution

Given information:

Thegiven information is:

Color	Red	Blue	Green	Yellow	Pink	Purple	Black
Group A	8	6	4	2	5	4	1
Group B	7	7	3	0	6	5	2

Calculation:

Let us consider the result of the survey question is shown below in the table;

Color	Red	Blue	Green	Yellow	Pink	Purple	Black
Group A	8	6	4	2	5	4	1
Group B	7	7	3	0	6	5	2

The results of survey question are not same because each sample is a random sample.From the above table we see that result of survey question in both class that is the Group A and the Group B, both are different Group A, 8 people chose red color, and in Group B: 7 people chose the red color In Group A, 6 people chose blue color and in group B, 7 people choose bluecolor. Green color is chosen by 4 people from Group A and 3 people from Group B. similarly others colors are chosen by the people of both group are randomly.

So, we can say that the result of the both group are random.

Thus, the result of the sample question is biased.

Therefore, the sample is a random.
