Probability/The Addition RuleQuestion 13During a 52-week period, a company paid overtime wages for 18 weeks and hired temporary help for 9 weeks. During 5 weeks, the company paid overtime and hired temporary help.
Are the events "selecting a week that contained overtime wages" and "selecting a week that contained temporary help wages" mutually exclusive? {#1}
If an auditor randomly examined the payroll records for only one week, what is the probability that the payroll for that week contained overtime wages or temporary help wages? {#2}

Not mutually exclusive. For five weeks the events overlap.
