Answer
Explanation:
Step1: Calculate total number of pedestrian deaths
The total number of pedestrian deaths is the sum of all the values in the table. So, $46 + 78+242 + 618=984$.
Step2: Calculate number of deaths with non - intoxicated drivers
The number of deaths with non - intoxicated drivers is $242+618 = 860$.
Step3: Calculate the probability
The probability $P$ that the driver was not intoxicated is the number of deaths with non - intoxicated drivers divided by the total number of pedestrian deaths. So, $P=\frac{860}{984}\approx0.8740$.
Answer:
$0.8740$
