Math Problem Statement
A computer software firm maintains a telephone hotline service for its customers. The firm finds that 40% of the calls involve questions about the application of the software, 45% involve issues of incompatibility with the hardware, and 15% involve the inability to install the software on the user's machine. These three categories of problems can be resolved with probabilities 0.90, 0.30 and 0.80, respectively. Knowing that an incoming call that does not involves question about the application of the software cannot be resolved, then the probability that it involves issues of incompatibility is
