Question

the table summarizes results from pedestrian deaths that were caused by automobile accidents.

driver intoxicated?	pedestrian intoxicated?
yes	63	86
no	233	597

if one of the pedestrian deaths is randomly selected, find the probability that the pedestrian was intoxicated. (round your answer to 4 decimal places.)
probability =

Explanation:

Step1: Calculate total number of pedestrian deaths

$63 + 86+233 + 597=979$

Step2: Calculate number of intoxicated pedestrians

$63 + 233 = 296$

Step3: Calculate the probability

The probability $P$ that a randomly - selected pedestrian was intoxicated is given by the formula $P=\frac{\text{Number of intoxicated pedestrians}}{\text{Total number of pedestrian deaths}}$. So $P=\frac{296}{979}\approx0.3023$

Answer:

$0.3023$
