Is the following argument valid or invalid?

All non-octopi are orange;

Shannon is not orange;                 

Therefore, Shannon is an octopus.


I really need help with this question! Thank you!

This is a valid argument.

As everything that isn't an octopus is orange, and since Shannon is not orange, Shannon much be an octopus.
