You choose one marble.
A bag contains 1 4 red marble.
The sample space for the second event is then 19 marbles instead of 20 marbles.
A bag contains 1 blue 2 green 3 yellow and 3 red marbles as shown.
Find 3 1 0 times the probability that the transferred ball is black.
A bag contains 4 red marbles and 2 white marbles.
Let x the number of draws.
Total number of marbles in the bag is 3 4 7.
Another marble is taken from the bag.
You draw a marble at random without replacement until the first blue marble is drawn.
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.
Bag b contains 9 black marbles and 6 orange marbles.
The problem asks for the probability of rr or bb.
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.
Choosing a blue green or yellow marble the probability of choosing a penny from the 1980s from the bag of pennies without looking is mc003 1 jpg.
Two marbles are drawn without replacement.
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.
Are these events inclusive or mutually exclusive.

A marble is selected kept out of the bag and then another marble is selected.
A jar contains 4 black marbles and 3 red marbles.
A marble is taken at random and replaced.
One ball is transferred from bag i and bag i i and then a ball is drawn from bag i i.
Work out the probability that the two marbles taken from the bag are the same color.
Bag i contains 3 red and 4 black balls and bag i i contains 4 red and 5 black balls.
The ball so drawn is found to be red in colour.
