Let's solve this step by step!

Problem Breakdown:

We are tasked with finding the probability that the driver was not intoxicated but the pedestrian was intoxicated, based on the given data table.

Step 1: Extract data from the table.

From the table:

• Driver NOT Intoxicated AND Pedestrian Intoxicated: This corresponds to 270 cases.
• Total number of cases: 978 (sum of all rows and columns in the table).

Step 2: Probability Formula.

The probability of a specific event occurring is:

$P = \frac{\text{Favorable Cases}}{\text{Total Cases}}$

Here: $P = \frac{270}{978}$

Step 3: Perform the Calculation.

$P = \frac{270}{978} \approx 0.2761$

Convert this to a percentage: $P \times 100 = 27.6\%$

Final Answer:

The probability is 27.6%.
