X is the count of tosses until the first head. This is a random variable of some distribution. I wonder what? We have that.

Expected Values Using Bernoulli Trials - Flipping a Coin This may be a clue as to the name of our mystery distribution. You expect in two flips to get one head. 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. But in gamblers' fallacy we believe that because of an event occurring in one direction like obtaining heads in a coin toss then the next event must go in the opposite direction tails. The law of averages states that over repeated independent trials we will observe a value on average that is close to our expectation.

We can specify a random variable, x, which associates a number with all possible outcomes of the roll of a die. In it, you'll get: I learned of this clever approach here: Given any such iterative process where each iteration is identical and independent of the previous ones and has nonzero probability of stopping, and the desired quantity being the cumulative sum of values of each iteration, where there are upper and lower bounds on the value of all iterations, the desired quantity has finite expectation, for the reason that a series similar to the infinite sum in the other answers converges. The first part adjusts that for the sample size. Note Given any such iterative process where each iteration is identical and independent of the previous ones and has nonzero probability of stopping, and the desired quantity being the cumulative sum of values of each iteration, where there are upper and lower bounds on the value of all iterations, the desired quantity has finite expectation, for the reason that a series similar to the infinite sum in the other answers converges. The value that x takes on in any one roll or coin toss has a known probability.
