But that wasnt the question you asked.

I saw it a A guesses B coin as either H or T. And B guesses A coin as H or T. Both is 50/50 unless they know the outcome of the other why they can't as no communication.
If A Gets H they guess H
If A gets T they guess T

If B gets H they guess T
If B gets T they guess H

They agreed this strategy beforehand.

A goes first. Coin is flipped and she gets Heads. Declares Tails.

B goes next,

If he gets Heads, he declares Heads, so B guesses A correctly. If he gets Tails, A is right.

Question 2: you are in the dark, and you want to put on a pair of socks. You have 7 pairs of socks.

You remember that you have forgotten to match the socks yesterday, so they are all loose. How many socks must you take out to ensure that there will always be at least one matching pair?

QM
"Taking out" ie removing 6 socks will ensure you have 8 socks on the bed, one of which must definitely be a matching pair.

Depending on your definition of "taking out" - so 6.
