This argument is invalid. This truth table shows how
Take note of line 12, which is marked in red. This line has true premises (T) but a false (F) conclusion. This occurs when...
G = false (F for false)
J = true (T for true)
Q = false (F for false)
H = true (T for true)
This line (line 12) tells us we have an invalid argument. An invalid argument occurs when all premises are true but they lead to a false conclusion.
