I know that I can say ∃x(P(x)) which means there is at least one x for P(x), but how do I express for exactly one?
Here's the questions:
(a) Not everyone in your class has an internet connection. (b) Everyone except one student in your class has an internet connection.
So for the first one I wrote:
"For all x there exists an x (or more) such that an x does not have an internet connection" (where I is the state of having an internet connection)
(b) Don't know how to express
I could be wrong please correct me since i'm pretty new to expressing this all mathematically
Thanks for help
