It is known that binary words containing no $k$ consecutive 1s are enumerated by $k$-step Fibonacci numbers. In this note we discuss the expected value of a random bit in a random word of length $n$ having this property. This expectation can reveal new properties of some telecommunication protocols or interconnection networks.
