Question

Of the 58 employees in a firm, 8 are considered support staff, and 7 of the employees have more than five years of experience. All of the support staff
have less than five years of experience. Consider the two events, J and K.
• Event J: Employee is considered support staff.
• Event K: Employee has more than five years of experience.
How many outcomes are possible for the complement of the union of Events J and K?

Answer 1

Using statistical concepts, it is found that the number of outcomes that are possible for the complement of the union of Events J and K is of 43.

What is the union of events J and K?

It means that at least one of event J or event K is true, hence, it is composed by employees that are either considered support staff(less than 5 years of experience) or employees that have more than five years of experience, combining a total of 7 + 8 = 15 employees.

What is the complement?

The total number of outcomes of the union of J and K, plus the complement, add to the total number of 58, hence:

15 + x = 58

x = 43.

The number of outcomes that are possible for the complement of the union of Events J and K is of 43.
