Explanation:

Step1: Locate relevant cell

In the two - way relative frequency table, we need to find the cell corresponding to "Democrat" in the "Party Affiliation" column and "No Opinion" in the "Do You Approve of the Mayor's Job Performance" row.

Step2: Identify probability value

The value in that cell is the probability $P(\text{Democrat and no opinion})$. From the table, the value is $0.07$.

Answer:

$0.07$
