Answer:
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%
