If the statement if the sun is shining the its not raining and is assumed to be true is it reverse if its not raining then the sun must be shining and?

No, the reverse of the statement "If the sun is shining, then it’s not raining" is not logically valid. The reverse would be "If it’s not raining, then the sun is shining," which does not necessarily follow. It is possible for it to be cloudy or overcast without rain, even if the sun is not shining. Thus, the original statement does not imply its reverse.
