I am a little confused about the first two rules and how they may be different.
Rule One says: She Must take Japanese IF she does not take Russian. Ok..
~R -> J
~J -> R
Rule Two says: She cannot take Japanese if she takes MacroE..
M -> ~J
J -> ~M
In the video, rule one is presented as a not both; or that one of R or J must be in. Is the difference between why we can say that in rule one vs rule two because of the word "must" in the conditional? In rule two, it would seem that J & M certainly cant co-exist, but that they could also both be out...Thanks.
