A company published the results of a study that found that arrogant workers are more likely to have poor performance ratings. Suppose that % of all full-time workers exhibit arrogant behaviors on the job and that % of all full-time workers will receive a poor performance rating. Also, assume that % of all full-time workers exhibit arrogant behaviors and receive a poor performance rating. Let A be the event that a full-time worker exhibits arrogant behavior on the job. Let B be the event that a full-time worker will receive a poor performance rating. Complete parts a through c. Are the events A and B mutually exclusive? Explain.
A. No, because some full-time workers exhibit arrogant behaviors but do not receive a poor performance rating.
B. Yes, because some ful-time workers exhibit arrogant behaviors but do not receive a poor performance rating.
C. No, because some full-time workers exhibit arrogant behaviors and receive a poor performance rating.
D. Yes, because some full-time workers exhibit arrogant behaviors and receive a poor performance rating.

Part A: For every 1 cup of yellow paint, Garcia mixed 4 cups of red paint to make a shade of orange paint.   
Part B:  Garcia should add 1/4 cup of yellow paint to each cup of red paint to mix the same shade of orange.    
Part C: The unit price for each cup of red paint is $7.  6=$42, divide both sides by 6, 6/6=1, $42/6=$7, so 1 cup of red paint=$7.
