Question

the table summarizes results from 984 pedestrian deaths that were caused by automobile accidents. if one of the pedestrian deaths is randomly selected, find the probability that the pedestrian was intoxicated or the driver was not intoxicated. please enter a decimal to 4 decimal places. probability = enter an integer or decimal number, accurate to at least 4 decimal places (more...).

Explanation:

Step1: Calculate total number of cases

The total number of pedestrian - death cases is \(252 + 60+603 + 69=984\).

Step2: Calculate number of favorable cases

The number of cases where one of the driver or the pedestrian was not intoxicated is \(252+603 = 855\).

Step3: Calculate probability

The probability \(P\) that the pedestrian was intoxicated given that one of the driver or the pedestrian was not intoxicated is calculated using the formula for conditional probability. First, find the number of cases where the pedestrian was intoxicated and one of them was not intoxicated. That is \(60\). The probability \(P=\frac{60}{855}\approx0.0702\).

Answer:

\(0.0702\)
