So we want to determine if p, n, q, or r is logically equivalent to pnq or pnr.
00:16
So we want to use a true table to prove this.
00:21
So we need p, q, and r.
00:29
So we're going to have true, true, false, true, true, false.
00:35
True, true, false.
00:38
Then we have alternating true, false.
00:40
And then we have four truths, four falses.
00:55
So now we need a q or r.
01:05
And then once we have a q or r, we can have a q and n, i have pn, q or r...
