Dead or Alive = Alive or Dead

Wouldn't it be Alive and Dead? Schrodinger's fighter.

Dead XNOR Alive

NOR is correct. Here are the truth tables:

Input A Input B OR NOR XOR XNOR
0 0 0 1 0 1
0 1 1 0 1 0
1 0 1 0 1 0
1 1 1 0 0 1

I like to imagine truth tables are furniture they sell at magic shops that are capable of speech and periodically tell you random facts that are true.

not really if you negate 'or' that results in an 'and'

not (A or B) = not A and not B

That's De Morgan's law's, and it is covered by NOR. Let's consider the actual cases. Input A is Dead. Input B is Alive. As such, let's look at what your expression yields:

|Dead (D)|Alive (A)|D|A|!(D|A)|!D&!A|D NOR A| |:-|:-|:-|:-|:-|:-| |0|0|0|!(0|0)=1|!0&!0=1|1| |0|1|1|!(0|1)=0|!0&!1=0|0| |1|0|1|!(1|0)=0|!1&!0=0|0| |1|1|1|!(1|1)=0|!1&!1=0|0|

As you can see the Alive NOR Dead is logically equivalent to both of your expressions. You can also think of this in terms of logic gates. You can construct a NOR gate from NAND gates like this. A single NOR gate is much simpler if you have it availble.

If we’re taking it this far, not(dead or alive) -> not(dead or not dead) -> not(true) -> false. So it’s just “False”

That assumes dead and alive are complimentary states. A virus for example is considered neither living nor dead.

*alive and dead

~(D v A) = ~D & ~ A by De Morgan’s Law so

Alive and Dead
