If the first marble drawn is red what is the probability the second marble is blue.
A bag contains 3 red marbles and 4 blue marbles two marbles are drawn at random without replacement.
Two marbles are drawn without replacement from a jar containing 4 black and 6 white marbles.
If three marbles are drawn out of the bag what is the probability to the nearest 1000th that all three marbles drawn will be blue.
The probability of selecting a red marble on the first draw is 0 5.
A bag contains 5 red and 3 blue marbles.
Two marbles are drawn without replacement.
Two marbles are drawn randomly one after the other without replacement from a jar that contains 3 red marbles 6 white marbles and 7 yellow marbles.
The probability of drawing 3 red marbles in a row from a bag of 3 blue and 4 red marbles without replacement is right at about 0 11 or about 11 in 100 if you want odds remember that probability.
Conditional probability a bag contains 3 red marbles and 4 blue marbles.
Work out the probability that the two marbles taken from the bag are the same color.
A jar contains 4 black marbles and 3 red marbles.
B a white marble is drawn first followed by a white marble.
A bag contains 3 red marbles 5 green marbles and 2 blue marbles.
A bag contains 3 red marbles and 4 blue marbles.
Find the probability of the following events.
Two marbles are drawn at random without replacement.
Theres a total of 12 marbles of which 3 of them are yellow so the odds of picking a yellow is 3 12 or 1 4.
Determine the probability that at least one is red.
A a red marble is drawn first followed by a white marble.
If you take that out you know have 11 marbles of which 2 of them are yellow so the odds of picking a yellow marble is 2 11 the odds of picking a yellow marble twice in a row is found like this 1 4 2 11 2 44 1 22 ans.
Total number of marbles in the bag is 3 4 7.
The probability of selecting a red marble and then a blue marble is 0 28.
Another marble is taken from the bag.
A bag contains 8 red marbles 6 blue marbles and 3 green marbles.
What is the probability of selecting a blue marble on the second draw given that the first marble drawn was red.
Two marbles are drawn simultaneously from the bag.
A marble is taken at random and replaced.
A 3 7 b 1 2 с d 2 7 3 conditional probability a bag contains 3 red marbles and 4 blue marbles.
The problem asks for the probability of rr or bb.
B find probabilities for p bb p br p rb p ww p at least one red p exactly one red 3.
P at least one red p rr or rb or br alternatively p at least one red 1 p no reds complementary events 1 p bb and so on.
Drawing simultaneously is the same as sampling without.
The probability is.
Two consecutive draws are made from the bag without replacement of the first draw.
