Hi all! I’m going through the formal logic chapter of the LR Bible and just have a quick question.
I know when given “No As are B” or A
B
We can infer A
not B
A
not B
A
not B
And not B
A
However since the original statement is reversible as a double arrow and also means “No Bs are A” or B
A I’m wondering if the following inferences are also valid:
B
not A
B
not A
B
not A
not A
B
Thanks so much!
