In addition, suppose that of the companies that use training for process improvement, 89% use training for employee retention. A company that uses training is randomly selected. a. What is the probability that the company uses training for employee retention and not for process improvement

Answer 1

Answer:

0.3081 = 30.81% probability that the company uses training for employee retention and not for process improvement

Step-by-step explanation:

56% employee retention.

38% for process improvement. Of those, 89% for employee retention.

a. What is the probability that the company uses training for employee retention and not for process improvement

The 56% is composed by:

x of 100 - 38 = 72%(not for process improvement)

89% of 38%(for process improvement).

We want to find x. So

$0.72x + 0.89*0.38 = 0.56$

$0.72x = 0.56 - 0.89*0.38$

$x = \frac{0.56 - 0.89*0.38}{0.72}$

$x = 0.3081$

0.3081 = 30.81% probability that the company uses training for employee retention and not for process improvement
