Consider the following premises. For all z, z is not an electrician. Charles is an electrician or it is windy. Can we infer the following from them? It is not windy.
 From the fact that for all z, z is not an electrician we can infer that Charles is not an electrician. Finally, from the fact that Charles is an electrician or it is windy, and that Charles is not an electrician we can infer that it is windy, which contradicts that It is not windy. Therefore, the answer is no.
