Please help me! *I do not just want the answer*
Use rules of inference to show that the hypotheses “If it
does not rain or if it is not foggy, then the sailing race will
be held and the lifesaving demonstration will go on,” “If
the sailing race is held, then the trophy will be awarded,”
and “The trophy was not awarded” imply the conclusion
“It rained.”
