This has been tested with thousands of flips and the side which faces up when flipped has a slight statistical advantage

There is no way of knowing for surebrEach flip may be a 50/50 chance that you get a head or a tail which means that, in theory, you should get 15 tails, but you'd probably have to flip way more than 30 times to get closer to a 50/50 result overall in reality

You're quite right John, it needs some thouht and insight

If the same trial is repeated many times it could hold true to 15 times on average

15 times on average

19/30 ? what about sample cases 2 to the power 30 ?
Comment from : @iitncompany

About 15 Though every thirty tosses would differ

On first go around it could be 13,14 or 16,17 What is the probability of 10 or 20 or even coming up heads or tails more that 5 times in a row? How many times of 30 coin flip go arounds would it come up 50-50 in a 100 tries? 4-5 times?

I worked in department call spc, statistical process controls We performed an experiment that ended with us knowing the longer the test is ran the closer to 50 within the bell shaped curve

I'd imagine that if you hold all the conditions equal for a small sample, the experimental would equal the theoretical But yes if the samples have random conditions, a large one would cause the experimental to approach the theoretical outcome

50-50

am I of track?
Comment from : @danielcase1046

50, give or take 20
Comment from : @danielcase1046

maximum likelihood estimator says the more tries, the closer to 50/50

The coin has no memory Each flip of the coin is 50/50

Use a two headed coin so it never happens Kidding aside, it could happen every time or not happen at all

There's no way to know It could very well come up tails 30 times The idea that it'll be a 15/15 split every time is a falsehoodbrIt's fun to watch gamers complain about this when they don't understand how they missed three 95 shots
