    Figure: Probability - Scenario Example

    Solution

    Sample Space

    S = {HHH, HHT, HTH, THH, HTT, THT, TTH, TTT}

     n(S)=8

    Event

    E= Getting at least one heads

    E={HHH, HHT, HTH, THH, HTT, THT,TTH}

     n(E)=7

    Probability

    $$ P(E) = \frac{n(E)}{n(S)}$$ $$P(\text{getting one heads}) = \frac{7}{8} $$
