Answer:

There is a 20% probability that the store selected does not violate the institute scanner accuracy standard

Step-by-step explanation:

70 company stores were investigared.

56 violated the institute's scanner accuracy standard.

70-56 = 14 did not violate the institute scanner accuracy standard.

If 1 of the 70 company stores is randomly selected, what is the probability that that store does not violate the institute scanner accuracy standard?

This is 14 divided by 70, so:

$P = \frac{14}{70} = 0.2$

There is a 20% probability that the store selected does not violate the institute scanner accuracy standard
