Company ABC has one thermostat, two boilers, and one water gauge. For a company to be properly heated, the thermostat and a minimum of one boiler must be operational (both boilers can also be operational). The water gauge is not a factor. History shows that each boiler is operational 72% of the time. The thermostat is operational 94% of the time and the water gauge is operational 87% of the time. Failures of either the thermostat, boilers or water gauge are independent of each other. What is the probability that company ABC is properly heated.
