A system may become infected by some spyware through the internet or email. 70% of the time the spyware arrives via the internet, 30 % of the time via email. If it enters via the internet, the system detects it immediately with probability 0.6. If via email, it is detected with probability 0.8. What percentage of times is this spyware detected?
