If I flip two coins 100 times, is there a 50/50 probability of getting heads or tails. True or false?
I know that if I flip two coins I will either get HH, TT, HT or TH.
P(H) is 0.75 for each flip with two coins
P(T) is 0.75 for each flip with two coins
But these probabilities are out of the four possible combinations, and I need them to be out of two, i.e. heads or tails:
So, what is the long term probability of getting either a heads or a tails in the long term? Well, I isn't it 0.5 for each? Because if I flip the coins 100 times and count up how many heads I get and how many tails I get, theoritcally, I should get half of them as heads and half as tails.
Does this sound right?
