What is p red then white.
A bag contains 1 4 red marble.
Another marble is taken from the bag.
Find 3 1 0 times the probability that the transferred ball is black.
Let x the number of draws.
What is the probability of selecting a green or red marble.
Since the probability of drawing a red marble from one bag is independent of the colour of the marble drawn from the other bag the probability is math frac34 times frac34.
A marble is selected kept out of the bag and then another marble is selected.
A bag contains 3 red marbles and 4 blue marbles.
Bag a contains 9 red marbles and 3 green marbles.
Bag b contains 9 black marbles and 6 orange marbles.
The ball so drawn is found to be red in colour.
Total number of marbles in the bag is 3 4 7.
For example a marble may be taken from a bag with 20 marbles and then a second marble is taken without replacing the first marble.
Work out the probability that the two marbles taken from the bag are the same color.
A bag contains 4 red marbles and 2 blue marbles.
The complement of this is the probability that both marbles are red.
Find the probability of selecting one green marble from bag a and one black marble from bag b.
A bag contains 4 red marbles and 2 white marbles.
You draw a marble at random without replacement until the first blue marble is drawn.
One ball is transferred from bag i and bag i i and then a ball is drawn from bag i i.
Two marbles are drawn without replacement.
A bag contains 1 blue 2 green 3 yellow and 3 red marbles as shown.
The sample space for the second event is then 19 marbles instead of 20 marbles.
A marble is taken at random and replaced.
A bag contains 9 green marbles 5 yellow marbles and 6 red marbles.
A if you repeated this experiment a very large number of times on average how many draws would you make before a blue marble was drawn.
