Then the probability of win is 1/3 while probability of loss is 2/3 each and every guess.
So in 13 trials, the expected number of wins is 4.
They have an equal probability
the probability of getting all N trials correct is (1/3)^N = 1/(3^N)
while the probability of getting all N trials wrong is (2/3)^N = 2^n/ 3^n
so 1/3^n vs (2^n) / 3^n ... which one do YOU think is more likely?
