Police report that when a driver is stopped on suspicion of drunk driving, the probability is 0.8 that the driver is given a breath test, the probability is 0.37 that the driver is given a blood test, and the probability is 0.24 that the driver is given both tests. What is the probability that a driver is given a breath test or a blood test or both? (That is, find the probability of the union).

BrAC BAC 0.7 0.5 1.13 0.22 0.82 Question 2. Prevention and detection of drinking and driving are major concerns of traffic Driver police. In the U.S. in 2012, nearly one-third of all traffic deaths involved 0.34 drivers with excessive blood alcohol concentrations (BAC). Investigative 0.26 authorities employ breath-alcohol analyzers, i.e. breathalyzers, to measure breath alcohol concentrations (BrAC) because the tests can be easily applied and do not require an attending physician to extract blood. Thresholds for 0.29 alcohol-impaired driving are...
