Casuality relations

by erjamit » Sun Jul 20, 2008 8:44 am
Hi,

I have difficulty grasping the casuality relationship. e.g

if A then B, implies if not B then not A.

if A then B, doesn't imply if not A then not B.

and similar ones.

Is there any link, document explaining these.

Thanks
Amit

HI erjamit,
if A then B,
A is the cause, B is the result,
so that not B mean that not A,
thats all,
:D
Please share your idea and your reasoning :D
