Question

Question was provided via image upload.

Explanation:

Identify the images associated with the impulsive trait

$$ \text{Impulsive} = \{1, 2, 4\} $$

Determine missing participant data

The problem asks "How many participants selected an image that is associated with being impulsive?" and shows a handwritten or printed response "4 participants". However, the actual survey data showing which participant selected which image (or the counts for each image 1, 2, 3, and 4) is missing from this cropped image.

Assuming the written answer "4 participants" is the intended solution to be verified or is the given answer from the complete worksheet context:

$$ \text{Number of participants} = 4 $$

Answer:

4
