If we have 2 bags containing marbles. bag a has 7 green and 6 black marbles. bag b has 8 yellow and 4 red marbles. if we pick randomly one marble from each bag, find
a.p(green and red)
b.p(black and yellow)
c.p(green and yellow)
d.p(black and red)
A.  (7/13)·(1/3)=7/39.    P=7/39 B.  (6/13)·(2/3)=12/39.   P=12/39 C.  (7/13)·(2/3)=14/39.   P=14/39 D.  (6/13)·(1/3)=6/39.    P=6/39
All the numbers from Bag B were written as thirds cause their probabilities could be simplified to make multiplying easier
