Explanation / Answer

I Just solve only 2.2

2.2.1) With three variables p,q and r that is true when p and r are true and q is false, and false otherwise

Sol) p ^ ~q ^ r

2.2.2) With three variables p,q and r that is true when exactly one of the three variables is true, and false otherwise

Sol) (p ^ ~q ^ ~r) v (~p ^ q and ~r) v (~p ^ ~q ^ r)

2.2.3) With three variables p,q and r that is never true.

Sol) (p ^ ~p) v (q ^ ~q) v (r ^ ~r)

2.3) Prove that the proposition "if it is not hot, then it is hot" is equivalent to "it is hot"
