1. Within the hypothetical ADJO Police Department, the probabil- ity that an officer will receive a management promotion by the age of 35 is 0.20 and that a promotion will be received by the age of 50 is 0.50. The probability of receiving both promotions is 0.15. Given these data, what is the probability of receiving at least one promotion?
2. Refer to Table 9.3 to solve this problem. Determine and list the complements of both the marginal probabilities and the joint probabili- ties contained within Table 9.3.
