90 :p

Nah just joking, but seeing as your an army veteran (I think...well, I hope :)), I'd say around 50-60?

hihihi, i like it

p → q, p ˅ ˥p, q ˅ p, (r ˅ p) ˄ (q ˅ r), ˥p ˅ q

is this conclusion valid? or not?

The conclusion can be true or false, but not valid. The argument can be valid or not.

Is this your argument?

{(p → q) & (p V ˥p) & (q V p) & [(r V p) & (q V r)]} → (˥p V q)

If yes, the argument is valid. This means that if the premises are true, then the conclusion is true as well.

90? Rofl... In my 20's... Oh and it was USMC by the way... Not to be confused with the Army... I know all of the armed forces get chalked up together, but it makes a difference to the people who were in...

premises
∀x(Ax → Bx), ∀x(Cx → ˥Dx), ∀x(Ex → Ax), ∀x(Bx → ˥Fx), ∀x(˥Ex → Cx)
conclusion
∀x(Fx → ˥Dx)
