(a) *[tex \LARGE \ \ \ \ \ \ \ \ \ \ (p\ \small{\wedge}\LARGE\ q\ \small{\wedge}\LARGE\ r)\ \small{\vee}\LARGE\ (\neg{p}\ \small{\wedge}\LARGE\ \neg{q}\ \small{\wedge}\LARGE\ \neg{r})].


In other words, all of p, q, and r must be true OR they all must be false.


(b) At least one of p, q, and r must be true and at least one must be false.
