Determine whether the following two compound propositions are logically equivalent. Show/demonstrate that your answer is correct and explain. p → q {“version”:”1.1″,”math”:”p\rightarrow q “} q → p {“version”:”1.1″,”math”:”q\rightarrow p “} It is intended that you be able to upload your work here and use whatever apps you need to do so. However, if you run into any issues doing so with Honorlock, you may email me your work or upload to “assignments”. Be sure that you have clearly labeled everything, and write something in the textbox so that I know (e.g. “I uploaded this problem to D2L and labeled it ‘problem 2 the problem about ____”). 

Identify the contrapositive of  r → s {“version”:”1.1″,”math”:”r\rightarrow s “}

 Write an expression logically equivalent to the following expression and that doesn’t use the arrow (if-then) symbol. Make your expression as simple as possible. Show all your work.  ¬ ( p → q ) {“version”:”1.1″,”math”:”\neg (p\rightarrow q)”} It is intended that you be able to upload your work here and use whatever apps you need to do so. However, if you run into any issues doing so with Honorlock, you may email me your work or upload to “assignments”. Be sure that you have clearly labeled everything, and write something in the textbox so that I know (e.g. “I uploaded this problem to D2L and labeled it ‘problem 2 the problem about ____”). 

OPTIONAL: If you want the possibility of partial credit for wrong answers to the other question on this page, upload your work or give your rationale here. You are also welcome to upload an audio explanation. Please ensure that any attachment is upright and legible.  For your uploads: please label the file with your name, and some indication of which problem it is (not the problem number, but something about the problem. The problems are shuffled so not everyone has the same number). It is intended that you be able to upload your work here and use whatever apps you need to do so.
