Look at the statement below. If a number is divisible by 8, it is an even number. Which of these is a logically equivalent statement? If it is not an even number, it is not divisible by 8. If it is not divisible by 8, it is not an even number. If it is an even number, it is divisible by 8. If it is not an even number, it is divisible by 8 I think it is B....
you have the usual statement If a, then b. This is the converse If b, then a. This is the inverse If not, then not b. This is the countrapositive If not b, then not a.
The countrapositive and the "usual statement" are the same logical equivalence.
Btw, countrapositive is equivalent to original, and converse is equivalent to inverse.
Got it!!! Thank you!!
