Exercise 2:
In 2011, Chevrolet sold three car models in Canada: Impala, Volt, and Corvette. Of
the vehicles sold, 50% were Impalas, 30% were Volts and 20% were Corvettes.
In the same year 12% of Impalas, 15% of Volts, and 25% of Corvettes had a
particular defect.
1. A 2011 Chevrolet has a defect. Which model is most likely to be affected?
2. A 2011 Chevrolet has a defect. What is the probability that Chevrolet Volt
is is not affected? Compute this probability using two different approaches.
