Question: (5 points) The Assistant Dean in our unit has decided that dress code is necessary for unit coherence. Unit staff are required to wear either blue shirts or red shirts. We have 9 men and 7 women in our unit. On a particular day, 5 men wore blue shirts and 4 other wore red shirts, whereas 4 women wore blue shirts and 3 others wore red shirt. Apply the Addition Rule to determine the probability of finding men or blue shirts in our unit.
