I have am trying to predict statistically the outcome of a process based on previous output. I somewhat compare it to a game of chance which everyone tells me I can't so I am asking for help because I believe in the game of chance it works too. There are only two outcomes in flipping a coin, heads or tails. The probability is 50% that for each. However, statisitically in "n" time, the outcomes will come very close to 50% each. If you flip a coin 9 times and it comes out heads each time is the probability of tails still 50% on the tenth flip? My belief even though it is a game of chance, the probability of tails coming out on the tenth flip is greater than 50% but I can't proof it. Thanks in advance for your help.
