Okay change the situation.
Suppose that the coins are a little magnets
and the table has hidden uniform magnetic field.
Then its works perfectly.
Quantum entanglement is solved.
you do not say?lol
try to read again
"If one coin become tail the other will be head always."
This is kind of magical coins. Entangled. The essense is not what you get.
The essence how magical coins behave randomess but connected. This works perfectly like real entanglement.
The dice metaphore is not really good because there is no measurement. Now I try another one.
Now we have two coin. The coin has two state: heads or tails . It is like up and down spin of electron.
The angle of measurement will be the tilt axis between coin and top of the table.
If you drop...
I get it. The big different between cards and entanglement is the randomness. Better you think that there are two dice.
If you roll a six with one the other dice has six also. This randomness is very important.
In this metaphore east to see that is impossible to send message with it.
Its works by classical Malus-law when p=a or p=b only.
/This called "spooky action at the distance" because you can rotate both polarizers freely./
But the result will be symmetrical only if half of sample will be p=a another half will be p=b.
Its looks like case of one photon and two...
This is not that easy like card games. First you need to know how polarizers works.
We have a Malus-law for polarizer.

Second important detail the independency of events.
"Two events A and B are independent (often written...
