Flipping heads 10 times in a row - Mathematics Stack Exchange
If I flip a coin 10 times in a row, obviously the probability of rolling heads ten times in a row is $\left (\frac {1} {2}\right)^ {10}$. However, I am not sure how to calculate the exact odds that I will have at some point rolled heads 10 times in a row during a series of n flips.

Probability of exactly two heads in four coin flips?
When you flip a coin four times, what is the probability that it will come up heads exactly twice? My calculation: we have $2$ results for one flip : up or down so flip $4$ times, we have $4\\

Expected value of the number of flips until the first head
35 Suppose we flip a coin until we see a head. What is the expected value of the number of flips we will take? I am pretty new to expected value, so I tried to evaluate it by multiplying the probability of each scenario with the number of flips it took to get there (like taking the arithmetic mean).

If every person on the planet flips coins until one person gets ten heads in a row, how long will it take to get the 10 heads in a row?

probability - Coin Flipping Riddle - Mathematics Stack Exchange
A sees a tail on coin flip 2 and 4 so he picks 3, B does the same. After running this on a computer simulation I get a 60% winrate. Although I don't fully understand why. Edit: a 70% chance of winning has been found on my Puzzling StackExchange duplicate post! Strategies so Far 70% chance of winning by @Jaap Scherphuis

Expected Number of Flips and Probability in a Coin Toss Experiment
If I get a tail on the first flip, the expected number of flips until I get a head is 2. This is because, after getting a tail, the coin is fair and the probability of getting a head on the next flip is 0.5. Therefore, on average, it would take 2 flips to get a head.
