Missing Premise Drill

Is it okay to have the premise swapped and still have the question correct? For example, P: y> not a (contrapositive would be a> not y) P: not a>b. contr. not b>a C: y>b. contra. not b>not y is it acceptable for me to put the second premise as not b>a and have the contr. as not a >b?

Hi @Tiffanysara,

Thanks for the question! Yes, it’s ok to have the premise swapped and still have the question correct. It doesn’t matter if you have the contrapositive or the actual statement; since they’re logically equivalent, it doesn’t matter.

Hope this helps! Feel free to ask any other questions that you might have.
