If we flip a fair coin four times and in order to win. In the game, you have to get the same result three times in a row (any three heads or three tails in a row is a win and) gets $100. What is the expected value of that game? What do you define as the expected value? What happens in the same case if we only have 35% of getting three tails in a row, but 65 of getting three heads in a row? What is the expected value of 35%? Can you explain to me the concept of expected value with these two examples? I am having problems understanding the concept.
