We have one server, one network switch, and one storage device. We will assume that

the server availability, the switch availability, and the storage availability are $95\%,90\%,$

and $85\%,$ respectively. The website will function normally only if the server, the switch,

and the storage are all operational. That is$,$ a failure of any individual hardware device

would cause the website to be unavailable. What is the availability of the website?
