Jack has a bag that contains 12 clear marbles and 6 red marbles.
He randomly draws 2 marbles, one after the other. What is the probability that
the first marble is clear and the second marble is red if the marbles are drawn
(a) without replacement?
(b) with replacement?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
(a) P = = reduce fractions.
(b) P = = reduce fractions.
Solved.
In case (a), the number of marbles and the contents does change after first draw.
In case (b), the number of marbles and the contents does not change after first draw.
It makes the difference between these cases (a) and (b).
