I repeated this experiment three times and I took notes and wrote down observations while doing it.
Attempt 1-TTTHHTHHHTTTHHTTTTHT
HHTTHHHTHTTTHHTHHTH
Answer- TTTHHTHHHTTTHHTTTTHT-fake
HHTTHHHTHTTTHHTHHTH-real
I noticed that it is very unlikely for 4 or more of the same result to come in a row.
Attempt 2-TTTTTHTHHTHTTTHTTTTT
HHTHTHTTTHTHTTHHHTH
Answer- TTTTTHTHHTHTTTHTTTTT-fake
HHTHTHTTTHTHTTHHHTH-real
Here I noticed that on an average both heads and tails are roughly the same amount of each time rather than a lot more of one than the other.
Attempt 3- HHHTHHTTHTTTTHTHTHHH
HTHHHHHHHTHTTTTHHHH
Answer- HHHTHHTTHTTTTHTHTHHH-real
HTHHHHHHHTHTTTTHHHH-fake
Here I proved that my previous two theories are correct although there are always possibilities of flipping twenty heads or tails even if it is only a minute possibility.
I then tried it on my mum, and I tried to make the fakes as realistic as possible and this is what I gave her-
TTHTHTHHTHHTTHTTHTHHH
HHTHTHTTHTTHHTHHTHTTT
What do you think is fake and what is real???
