The National Highway Traffic Safety Administration (NHTSA) collects traffic safety-related data for the U.S. Department of Transportation. According to NHTSA?s data, 10,426 fatal collisions in 2016 were the result of collisions with fixed objects (NHTSA website, https://www.careforcrashvictims .com/wp-content/uploads/2018/07/Traffic-Safety-Facts-2016_-Motor-Vehicle-Crash-Data -from-the-Fatality-Analysis-Reporting-System-FARS-and-the-General-Estimates-System -GES.pdf). The following table provides more information on these collisions.?

Assume that a collision will be randomly chosen from this population.?

a. What is the probability of a fatal collision with a pole or post??

b. What is the probability of a fatal collision with a guardrail??

c. What type of fixed object is least likely to be involved in a fatal collision? What is the probability associated with this type of fatal collision??

d. What type of object is most likely to be involved in a fatal collision? What is the probability associated with this type of fatal collision?
