'If jack attends, mark must attend'
my deduction: J > M contrapositive : ~M > ~ J
can I also conclude that it is possible for M to attend and jack attend or not attend? M > ~J or M > J
In other words the rule doesn't really really tell us anything about what could happen if mark attends?
Thank you in advance!
