digital video recorders (DVRs) in an inventory are known to be defective. What is the probability you randomly select an item that is not defective?

76%

Explanation:

Based on the information provided within the question it can be said that in this scenario the probability you randomly select an item that is not defective would be 76%. This can be calculated in the following way:

50-12=38 (Number of recorders in working condition)

(38) / (50) = 0.76

The probability is: 0.76

Now we times this decimal by 100 to get the percent.

0.76 * 100 = 76%
