# State Machines - What happens to 'Don't Care's in the Output?

This is referencing the article about state machines on allaboutcircuits.com In their state table, they have a 'Don't Care' listed under the output for the state 11. However, in their k-map of the output column, they listed a '0' under 11, instead of a don't care. Why is that?

• That's strange. I would rather use $1$, so $Y=B$. – Eugene Sh. May 1 '18 at 21:31
