The three inspections remain independent. Each class of defect is counted separately. Each defect count is compared to its corresponding accept-reject numbers. Should not be combining the accept-reject number or defect counts.
I am not sure you can say that the inspections remain independent. The process might be independent, but the defects might not be.

For example, if you have 3 classes of defects

Low - Visual Issue
Medium - Functional Issue
High - Safety Issue

The same part can have 0, 1, 2 or 3 defects though they each count towards their respective counts, the presence of a type of defect might lead to the presence of another type of defect.
