Do this as an exercise to prepare for the quiz.

In the textbook Logic and philosophy, go to p. 63, exercises 3-4
On the left-hand side, there are sentences, and on
the right-hand side, there are sentence forms (a- q). Is a sentence a substitution instance of each of the sentence
forms on the right? Consider sentence #7
~A v (B
⊃
C)
It is a substitution instance of the sentence forms a, c, e, l.
Why? Run #7 through each sentence form. Do this as an exercise to prepare for the quiz.
FOR EACH OF THE TWO SENTENCES BELOW, LIST ALL OF THE SENTENCE FORMS (in exercises 3-4, p. 63)
For, WHICH IT IS A SUBSTITUTION INSTANCE. Don’t write the sentence form–just write the letter which precedes
it.
This is the HOMEWORK below I need it in a word document as a table
1. ~ ~ [ ( A & ~A)
⊃
~ A]
2. ~~A v ~ (B & ~C)
