Consider the drivers who are suspected of driving under the influence of alcohol. Police use two techniques to check level alcohol: a breath test or a blood test. They use a breath test for 90% of cases, a blood test for 10% of cases, and both techniques are used for 9% of cases. Consider a suspect of driving under the influence of alcohol, and define the events "using a breath test" and `using a blood test". Are these events independent? O no O yes O given information is insuffisant
