 There are two ways in which we can deal with this.

 We can model this using an Euler diagram representation of
 an example component with three failure modes\footnote{OK is really the empty set, but the term OK is more meaningful in
 the context of component failure modes} $\{ B_1, B_2, B_3, OK \}$ see figure \ref{fig:combco}.
