I am not sure how to compile the contingency table from probabilities given.
Each yr ratings are compiled concerning the performance of new cars during the first 90 days of use. Suppose that the other cars have been categorized according to whether the car needs warranty - related repair (yes or no) and the country in which the company is based is Us or Non US. Based on the data collected, the the probability that the new cars need warranty repair is 0.04, the probability that the car is manufactured by a US based company is 0.60 , and the probability that the new car needs a warranty repair and was manufactured by a US based Company is 0.023.
Construct a contingency table or a Venn Diagram to evaluate the probabilities of a warranty related repair:
What is the probability that a new car selected at random:
a. Needs warranty repair
b. Needs warranty repair and was manufactured by a US based Company.
c. Needs a warranty repair or was manufactured in the US
d. Needs warranty repair or was not manufactured by a US based Company.
This solution provides a complete computation of the given statistics problem formatted in Excel.
