A box contains three marbles one red one green and one blue.
A box contains 2 red marbles and 98 blue ones.
Consider an experiment that consists of taking one marble from the box then replacing it in the box and drawing a second marble from the box.
Explain and justify each step carefully.
What s the fewest number of draws i have to make in order to have better than a 70 chance for a red marble to appear at least once.

Find the sample space if the first marble is not replaced before the second is chosen.
A first marble is chosen its color is recorded and then it is replaced in the box and a second marble is chosen and its color is recorded.
What is the probability that it came from the first box.
A box contains 2 red marbles and 98 blue ones.
A bag contains 1 blue 2 green 3 yellow and 3 red marbles as shown.
Find the sample space.
One box is selected at random and from that bag one marble is drawn.
A draw the tree diagram for the experiment.
A box contains 6 red and 5 blue marbles.
A box contains 3 blue and 2 red marbles while another box contains 2 blue and 5 red marbles.
Draws are made at random with replacement.
A box contains 3 blue marbles 4 red 6 green marbles and 2 yellow marbles.

P two tails foll0wed by one head.
What is the probability that the marble drawn is blue.
Repeat for the case in which the second marble is drawn without replacing the first marble.
P three tails 18 125.
Describe the sample space.
If two marbles are drawn at random what is the probability that at least one is green.
A box contains three marbles one red r one green g and one blue b.
Two marbles are drawn without replacement.
A marble drawn at random from one of the boxes turns out to be blue.
