To estimate the total number of books Marissa has read in 4 years, we first need to calculate the average number of books she has read per month based on the given sample.

The sample provided shows the following number of books per month:

- 4
- 1
- 3
- 3
- 2

Let's calculate the average:

1. Sum of the sample:
\( 4 + 1 + 3 + 3 + 2 = 13 \)

2. Number of months in the sample:
There are 5 months in the sample.

3. Average number of books per month:
\( \text{Average} = \frac{13}{5} = 2.6 \) books

Now, we'll estimate the total number of books Marissa would read in 4 years. There are 48 months in 4 years (12 months per year x 4):

4. Total estimate over 4 years:
\( 2.6 \, \text{books/month} \times 48 \, \text{months} = 124.8 \)

Rounding to the nearest whole number gives us:

**125 books**

So the correct response is **125 books**.
