Thread: Please help me solve the problem

problem:
An advertisement for a tennis magazine states, “If I’m not playing tennis, I’m
watching tennis. And if I’m not watching tennis, I’m reading about tennis.” We can
assume that the speaker cannot do more than one of these activities at a time. What
is the speaker doing?(Translate the given sentences into formal language; consider
the possible truth assignments.)

Sorry, but the last sentence says what to do, so what is your obstacle?
