Hi i was wondering if someone could help me
there are 9 marbles , with 4 being yellow
the probability of drawing a yellow is ... 4 / 9
the two drawings are independent events
... the 1st drawing doesn't affect the 2nd
the probability of two yellows is the product of the individual drawings
p(2 y) = 4/9 * 4/9
