Question:

For each of the following arguments, use the STTT to determine whether the argument is valid or invalid. For some of these arguments, Steps 2 C , 3 C , and 4 (i.e., the C-Sequence) will be most efficient; for some of these arguments Steps 2 P , 3 P , and 4 (i.e., the P-Sequence) will be most efficient.

(P₁): M ⊃ (N ꓦ O)
(P₂): N ⊃ (P ꓦ Q)
(P₃): Q ⊃ R
(P₄): ~ (R ꓦ P)
∴ ~ M
