Assume that two employees have to be fired from group of seven:
• Amy, female, age 35
• Bob, male, age 41
• Chad, male, age 43
• Diana, female, age 44
• Elvis, male, age 49
• Frank, male, age 61
• Ginger, female, age 62
Assume for now that the company chooses the two employees to be fired at random, so all possible pairs of people have the same probability of being fired.
1. Determine the probability (both as a fraction and a decimal) that the average age of the employees selected is older than 50.
