To calculate the marginal distribution of individuals who are underweight, we need to find the proportion of individuals who are underweight out of the total number of individuals.
From the table you provided, the total number of individuals who are underweight is 130 (93 males + 37 females), and the total number of individuals is 1000.
Now we calculate the proportion of underweight individuals:
\[
\text{Proportion of underweight individuals} = \frac{\text{Number of underweight individuals}}{\text{Total number of individuals}} = \frac{130}{1000} = 0.13
\]
To express this as a percentage, we multiply by 100:
\[
0.13 \times 100 = 13\%
\]
Therefore, the marginal distribution of individuals who are underweight is **13.0%**.
The correct answer is **3) 13.0%**.
