Quick Question - Contrapositives in AR
« on: March 27, 2005, 07:26:04 PM »
Apparently i've made a big mistake... and i think i just figured it out;

original statement: F1 -> G2 

 the contrapositive depends on what type of game im in correct?

if it's a linear game the contrapostive would simply be ~G2 -> ~F1 (not G2 -> not F1)

however, if it's a grouping game (two boats for example) the contrapositive would be   G1 -> F2 (which is the same as ~G2 -> ~F1)

yes?

Yes and that inference will answer at least a question or 2
