You can access Internet from campus only if you are a CS major or you are not a freshman
How can the above English sentence be translated into a logical expression?
I think this is biconditional but in the book by Kenneth Rosen (7th edition, example 12 on page 11), it is written as conditional.
My solution is the following:
P = You can access Internet. Q = CS major. R = Freshman. So, it should be P <=> (Q + !R)
But in the book it is written as P => (Q + !R)
What seems like the correct answer? I know that conditional is a subset of biconditional. But shouldn't biconditional be the stricter solution?
