regardless of how many coins are flipped, the chances are always 50%. Each coin flip counts as a separate instance and has no effect on the previous (or next) coin flip.
A better thing to try would be to find one of these: https://en.wikipedia.org/wiki/4-sided_die (call a number) and if you get that number, that's the chances we have at getting our pick.
--note: since I'm a D&D nerd and happen to have one of these at my desk at work, I tried it. Called a 2, got a 3. Tried it again, called a 4, got a 4! *We're totally getting that pick!*
No,
The chances of 2 heads in 2 flips = 25%.
The chance getting 2 tails in 2 flips = 25%
The chance of getting heads + tails = 25%
And the chance of getting tails + heads = 25%. Adds up to 100%.
You're right that each flip is an independant trial of 50% probability.
