Question

(a) Determine whether the following argument is valid: p =r 9 + (pva) (b) Determine whether the following argument is valid: pr 9 → (avr) .

Answer 1

The solution for part (a) is-

Thus from the above table we can determine that following argument is invalid.

7일|7Bvql 에 2M "BM시B+%)^^qM AIFFFFㅜㅜㅜㅜ 9FFFT FFIT FFT FT FT - EFFFFFFF SFFFFFFF | FFFFFFFF FTFTTTF TTTTTTT1

The solution for part (b) is

Thus from the above table we can determine that the argument is invalid.

-9 |gv-4|p>* |오게 19V 7에^(PAn)^2+게 PIFFFFㅜㅜㅜㅜ AIFFFFF TT AFTFTFTFT FFFFFFFFF TFTTTTT FFFFFFF |FTTTFFFF FFFFFFF FFFFFFFF

Now let us see the basic tables of operations we have used above-
