In this case p represents "n> 2" and q represents "n²> 4." Thus if n =3 then p is true and q is true. (a) Find another value of n that makes p true and q true. (b) Find a value for n that makes p false and q false. (c) Find a value for n that makes p false and q true. (d) Find a value for n that make p true and q false. Explain any problems you have.
