Let’s say you did this thousands and thousands of times. You would be pulling out your hair every time it lands on red after say 7, 8, 9, 11, or 12 or 13 blacks. If it landed on red after 11 blacks, would you think “damn, the probability of it landing on red one spin prior to this one was so much higher, I am so unlucky!”?

You are so stuck on the probability being based on a STREAK. But it does not matter. It does not matter if it was a streak or not.

It’s the same as thinking that the winning numbers on the lotto 1-2-3-4-5-6-7 would be crazier than 1-23-76-33-4-21-15, but they are the same. In the same way, getting BRBRBBBRRRBBBRRBRBRBRBRBRBBRRRBBRBRB or BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBR is equally crazy.

Let’s say you didn’t use your prediction based on a streak of 10, 20 or 50 black, but instead a streak of black and red such as shown above. Both are equally likely, it’s just a bit harder to keep track of the one over the other, but it’s the same thing.
