Question

the table summarizes results from 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. (round your answer to 4 decimal places.)
probability =
driver intoxicated? pedestrian intoxicated?
yes no
yes 52 70
no 271 596

Explanation:

Step1: Calculate total number of pedestrian deaths

$52 + 70+271 + 596=989$

Step2: Calculate number of intoxicated pedestrians

$52+271 = 323$

Step3: Calculate the probability

Probability = $\frac{323}{989}\approx0.3266$

Answer:

$0.3266$
