To find the marginal distribution for left-handed people, we need to calculate the proportion of left-handed people relative to the total population.

From the provided data, we see that the total number of left-handed people is 12 and the total number of people (both left-handed and right-handed) is 75.

The marginal distribution of left-handed people can be calculated as follows:

\[
\text{Marginal distribution for left-handed} = \frac{\text{Number of left-handed people}}{\text{Total population}} = \frac{12}{75}
\]

Calculating this gives:

\[
\frac{12}{75} = 0.16
\]

To convert this to a percentage, we multiply by 100:

\[
0.16 \times 100 = 16\%
\]

So the marginal distribution for left-handed people is **16%**.

The correct answer is **1) 16%**.
