Answer: 0.051
Step-by-step explanation:
In order to find the probability that two different pedestrian deaths were both involved in pedestrians that were intoxicated, we need to find the probability of this specific event occurring out of all possible events. To do this, we can use the formula:
Probability = (Number of favorable outcomes) / (Total number of possible outcomes)
First, we need to find the number of pedestrian deaths that involved intoxicated pedestrians. We can see from the table that 51 pedestrian deaths were caused by an intoxicated driver and a pedestrian who was also intoxicated.
Next, we need to find the total number of possible outcomes. We can see from the table that there are a total of 51 + 83 + 263 + 592 = 999 pedestrian deaths.
Therefore, the probability that two different pedestrian deaths were both involved in pedestrians that were intoxicated is:
Probability = 51 / 999 = 0.051
Rounded to four decimal places, the probability is 0.0510
