x is in this case a stochastic variable, you can't assign a value to it.

Probability is not involved, it all depends on how they are flipped.

There are only two possible outcomes: Heads/Heads, Heads/Tails. Therefore the probability of having both land on heads is 50%.

The coin flip takes place in a universe in which there exists a true and perfect scientific law that cannot be contradicted or evaded; this law is basically Alpha and Omega of this universe:

LAW OF FLIPPING A SINGLE COIN TWICE IN ONE SESSION
Whenever a coin is flipped twice and only twice in a single session, the first flip will land heads, and the second flip will land either heads or tails. The first flip involves NO CHANCE- it will ALWAYS land heads. The second flip has a 50% chance of landing heads and a 50% chance of landing tails. The coin will always fall flat side down. How the coin is flipped has absolutely no effect to the outcome of the landing. The coin will land on a flat surface.

It has nothing to do with probability, all to do with how the dice is thrown.

Also there's no guarantee that it would land on any number.

Let's say you NEVER flip a coin,
Let's say that coins do not exist,
What is the probability of the coin landing on heads twice in a row if the chance of landing heads is 50%?
