Tell if this Argument is valid (Propositional Logic)?
P = If a man is bachelor he is unhappy
Q= if a man is unhappy he dies young

C = so the conclusion will be Bachelors die young

is his right ?

This we have to write this in this form is this correct ----> means implies
Q ---> Q
Q
----------------
R
----------------

or

P --->q
Q --->R
--------------
P----->R
--------------
is this right ???
