You might need to use the distributive law for disjunction and conjunction .
For example, (A/\B)\/(A/\~B) = A/\(B\/~B) = A
Additionally, A->B equals ~A\/B (ex.((A->B) <-> (~A\/B))).
After simplifying your formula, you might need to verify the result using a truth table.
Hello, lozgur!
Vagabond is absolutely correct.
I'll run though the steps and hope you know the reasons.

Simplify: .![\bigg\{\bigg[(p \wedge q \wedge r) \vee (p \wedge q \wedge \sim r)\bigg] \vee\sim q \bigg\} \to s](http://latex.codecogs.com/png.latex?\bigg\{\bigg[(p \wedge q \wedge r) \vee (p \wedge q \wedge \sim r)\bigg] \vee\sim q \bigg\} \to s )
Inside the brackets: .

The problem becomes: .![\bigg[(p \wedge q) \:\vee \sim q\bigg] \to s](http://latex.codecogs.com/png.latex?\bigg[(p \wedge q) \:\vee \sim q\bigg] \to s)

thank u very much friends for helping and sharing the solution (ı dont know advenced level english but ı know upper-intermeiated so maybe ı did some mistake writing ıam hoping u can understand. )
Question:
For each of these sets of premises, what relevant conclusion or conclu-
sions can be drawn? Explain the rules of inference used to obtain each
conclusion from premises.(a) "If I eat spicy foods, then I have strange dreams." "I have strange
dreams if there is thunder while I sleep." "I did not have strange
dreams."
(b) "I am dreaming or hallucinating." "I am not dreaming." "If I am
hallucinating, I see elephants running down the roads."
ı instaled this statement:
(a)
p:I eat spicy foods
q:I have strange dreams
r:there is thunder while I sleep
(p->q)/\(r->q)/\~q
do ı solve [(p->q)/\(r->q)/\~q] this statement for this question? ı dont understand what this question say
ı could do it (Clapping)(Clapping)
