Problem
Three children have been tossing a coin in the air and recording the outcomes. They have done this 10 times and have recorded 10 tails. Before the next toss they make these statements:
Jackson: “It’s got to be a head next time!”
Sally: “No, it always has an equal chance of being a head or a tail. The coin cannot remember what the outcomes have been.”
Amy: “Actually, I think it will probably be a tail again, because I think the coin must be biased. It might be weighted so it is more likely to give a tail.”
Discuss the statements of each child. Who do you think is correct?
