I just found the probability forum here on 2p2.
Saw where someone lined this:

in another discussion..

So 220 divided by 4096
I think there is a factorial formula for cumulative... Ie 3 heads or less
The pyramid is 100% based on this.. Your 220 is on the pyramid
Thanks. I wrote up a post before my last one that apparently didn't go through.
If I'm reading your data correctly, I see the bell curve shape.
Looks like 23% of the time you get 3-in-a-row 6 times out of 12 flips. That would be the...mode? And then 38% of the time we get +1/-1 (61% of the time, total). 85% of the time it will happen 4-8 times. It is concerning that 3 in a row happens 10 times, 2 in 100 times and 11 times 29 in 10,000.
For my case, a round would be a quarter of play. 3 rounds a game(Q2-Q4 skipping Q1), 12 rounds would be 4 games.
Having 6 in a row (24% of the time) looks like we basically have 3 scenarios, x= 1 unit
@ -110 odds
Worst case
G1Q2 miss -1.10X
G1Q3 miss -3.41X
G1Q4 miss -8.26X (cumulative)
G2Q2 miss -18.45X
G2Q3 miss -19.84X
G2Q4 miss -84.77X
G3Q2 hit win +85.77X
and
G1Q2 miss (N/A)
G1Q3 hit + 1x
G1Q4 miss no action
G2Q2 miss -1.10x
G2Q3 miss -3.41x
G2Q4 miss -8.26x
G3Q2 miss -18.45x
G3Q3 miss -39.84x(cumulative)
G3Q4 hit win +40.84x
and best case
G1Q2 hit + 1x
G1Q3 miss no action
G1Q4 miss no action
G2Q2 miss -1.10x
G2Q3 miss -3.41x
G2Q4 miss -8.26x
G3Q2 miss -18.45x (cumulative)
G3Q3 hit +19.45x
G3Q4 no action
7 misses would be up to -179.11x cumulative loss, 8 -> -377.23x, 9 -> -793.28x, 10 -> -1666.99x, 11 -> -3501.78x with each one being divided into 3 scenarios depending on if the first miss happens in Q2 (worst case), Q3 (best case) or Q4.
I'm guessing it wouldn't make a difference but I wonder if playing Q1 would change the numbers a bit. It sort of seems like it would because Q1 you have two teams who set the stage for the Q1 total score odd/even. Then Q2,Q3,Q4 are played according to that. Then Q1 of the next game, two different teams set the stage for Q1 and Q2-4, in my mind, are played off of that Q1 result.
Thinking about it mathematically though seems like Q4 from 1 game carried over into Q1 of the next game shouldn't make a difference since it's a coin flip each time. It's just if G1Q1 is 'odd' then I'm going to be playing 'even' for each of the following G1Q2-4 until it hits since I"m betting against 'odd' hitting 4 times in a row. If it does, then it kind of feels like G2Q2 resets, in a sense, and it doesn't make sense to get against it hitting again although technically it is the 5th coin flip in a row and we would still be betting against odd hitting for the fifth time in a row.
I'm guessing this is what it means when we say the coin flips are independent. Like, I could pick any 3 Qtrs at random from various games in the day and still expect the same chance of them all hitting the same value vs. if I pick any 3 that are played consecutively.
In the basketball game scenario though it seems like maybe it isn't entirely 50/50, odd or even, and any difference in those odds does depend on the two teams that are playing in the game.
Either way, interesting info.
