To solve for b, you need to isolate/get the variable "b" by itself in the equation:

A = h(a + b)       Divide h on both sides

\frac{A}{h}=\frac{h(a +b)}{h}

\frac{A}{h} =a + b      Subtract a on both sides to get "b" by itself

\frac{A}{h}-a=a-a+b

\frac{A}{h} -a=b

Of the 58 employees in a firm, 8 are considered support staff, and 7 of the employees have more than five years of experience. A
polet [3.4K]

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.

<h3>What is the union of events J and K?</h3>

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.

<h3>What is the complement?</h3>

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.
