An aircraft door has 3 components - a mechanical system and a hydraulic system which need to work in tandem for the door to operate, and in case the above system fails, there is also an electronic controller which can operate the door all by itself. The chances that the mechanical system, the hydraulic system, and the electronic controller work properly are 90%, 80%, and 95% respectively.
Given that the door fails to operate, what is the probability that the failure was due to the failure of only the mechanical system and the electronic controller?
