which of the following is not the converse of the statement: If a, then b..?

Question

a) if b, then a
b) b only if a
c) a if b
d) none of these

Answer 1

well, everything but a is not the converse.
if a=>b is the original statement,
b=>a is the converse,
~a=>~b is the inverse,
and ~b=>~a is the contrapositive.
b if only if a (a<=>b) is the biconditional.

Answer 2

if a then b means : if a is true , then b is true.

a) no, a = ' i am a boy', b = 'i am a human'
b) no, same example
c) no, same example
d) Yesssss

Answer 3

B
