    I was wondering given
    g = you are gulity = 0.85
    d = lie detector says you're lying = 0.94

    What would the probability of these pair be?
    1. p(g) and p(d)
    2. p(g) and p(~d)
    3. p(~g) and p(d)
    4. p(~g) and p(~d)

    I came up with these but I'm unsure by just multiplying..
    1. 0.799
    2. 0.051
    3. 0.141
    4. 0.009

    I'm not sure if I'm suppose to be using bayes rule or not.
