A Bag Contains 1 4 Red Marble

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. Answer by jim thompson5910 35256 show source. A jar contains 4 black marbles and 3 red marbles. You choose one marble.

Bag i contains 3 red and 4 black balls and bag i i contains 4 red and 5 black balls.
