If Adam learns from the teaching team that the past 3 years students have chosen coins and they have always landed heads, he should prefer the coin over the thumbtack and call it heads. I]. If Adam has access to a thumbtack identical to the Professor's thumbtack, he can experiment to learn about X and he should choose the thumbtack over the coin. Even if Adam doesn't experiment on a thumbtack, he should choose the thumbtack over the coin. IV. If the deal is changed to two tosses instead of one and calling whether both tosses end the \"Same" or \"Different\
