Quality assurance department of software house reveals that 6.5% of programming code contain logical errors. Quality check software is developed to analyze code and in a test, identifies the error in 90% of the code with errors and 5% of those without. If code is marked by the program as possibly having a logical error, what is the probability that the code DOES have an error?
