    joint probability

    from the first table i was able to calculate the second. But i don't know how to finish the first table. I did it on spss and got an answer, but i can't calculate it by hand. Can someone please help me..

    Oh and btw is this right:

    A is independent from B because
    P(A) = .351387054
    P(A|B) =  \frac{.351387054 \times .62351387}{.62351387} = .351387054

    thank you!!
