eli5 If an unbiased coin has a 50% chance of getting heads and 50% of getting tails. If you roll 10 times why is it unlikely for you to get 5 heads and 5 tails. From a probability standpoint, shouldn’t you guarantee that?
It’s likely you will, but not guaranteed. The 50:50 is independent of anything that has come before it, so even if it has landed heads 27 times in a row, the chances of it landing heads again is a still 50:50
