How likely is it that if you flip a coin it will land on heads or tails?

Most people assume the toss of a coin is always a 50/50 probability, with a 50 percent chance it lands on heads, and a 50 percent chance it lands on tails. Not so, says Diaconis.

Is it possible to get 78 heads in a row?

Is it possible to get 78 heads in a row when tossing a coin? Yes, it is possible to get 78 heads in a row since one coin toss does not determine the next coin toss.

How many heads does it take to flip a coin?

So, in a very technical/mathematical sense, if you flip a coin forever, then eventually you’ll get the same number of heads as tails. Technically the average return time is infinite. In practice 90\% of the time you’ll get an equal number within 64 flips (fact!), and if you don’t then stop anyway.

How many heads are there in a fair coin?

The original question was: Lets say we have a fair coin that is flipped a hundred times and at the end of the trial there have been 40 tails and 60 heads. At this time there have been 20 more heads than tails and it could be said that heads is “dominant”.

How many times can you flip heads and tails in chess?

Since that includes #-of-heads = #-of-tails, then eventually (in less than infinite time) you’ll always flip the same number of heads as tails. Even “better”, this will happen an infinite number of times.

How do you find the probability of a coin flip?

The probability that the 2N th coin flip is the first that brings the tally back to zero, P (2N), is the number of paths that didn’t come back to zero before, divided by the total number of paths. C N is the number of ways for the tally to be greater than or equal to zero.
