What is the frequency of brown-haired people in the sample?

A. 3 and 4
B. 2
C. 4
D. 3

Answer :

To find the frequency of brown-haired people in the sample, let's examine the data provided in the table:

Here is the information from the table about hair color:

1. Bob: Blonde
2. Cathy: Brown
3. Samantha: Brown
4. Robin: Black

Next, we'll identify which individuals have brown hair:

- Cathy has brown hair.
- Samantha has brown hair.

Thus, we count the number of people with brown hair:
1. Cathy
2. Samantha

The frequency of brown-haired people in the sample is therefore 2.

So, the correct answer is 2.
