# Math Help - joint probability

1. ## 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!!
