  1. Assuming all three coins are fair, you could use a probability tree or a table to list all possible outcomes (Ω) and calculate the probabilities accordingly.
    H=head
    T=tail

    All 8 possible outcomes
    HHH
    HHT
    HTH
    HTT
    HHH
    THT
    TTH
    TTT

    You can use the table to answer the above questions.
