Can someone explain probability to me?

If you flip a coin 100 times, the results will be around 50/50.

But what if you flip it and it comes up tails 20 times in a row. Doesn't that mean the probability of the next flip being heads is increased? Why not?

Ok /sci/, call it in the air.... Heads or Tails?

What is the probability that your call is correct?

If you flip a coin 2 times in a row and gets heads twice you would agree that the chance for this to happen is 50% probability. And if you flip it a third time it is 25% chance for heads and 75% chance for tails.

BUT.. if you wait one year and then flip the same coin, will it still be 25% chance for heads?

And what if you change the coin? Will the outcome still be the same of will it be reset?

This really grinds my gears.

Is anything truly random or is randomness only what humans are not capable of predicting?

Why is it that the chances of getting 100 tails in a row is less than getting 50 heads and 50 tails? If it's a 50-50 chance of getting a head, then the next flip will also be 50-50, and subsequently the next one would be too. Therefore, the chances of getting 3 heads in a roll would be 50-50, just as the chances of getting 1 head and 2 tails would be the same, right?
