From the condition we can determine how many marbles of each color were there in the jar.
There are red and blue marbles in a jar.
A random sample of n 3 marbles is selected from the jar.
The same number of red and blue marbles were added to the jar.
You can arrange the marbles however you like but each marble must be in a jar.
This means that the number of red marbles is 2 x since the red marbles are twice as more as the blue marbles.
A jar contains 10 red marbles and 20 blue marbles.
If the first two marbles are both blue what is the probability that the third marble will be red.
A bucket contains 60 marbles some red some blue and sone white the percentage of drawing a red is 35 and the.
According to the experiment are all outcomes equally likely.
Indeed we have these equations where r is the number of red marbles g is the number of green marbles and b is the number of blue marbles g b 6 1 all but 6 are red marbles r b 8 2 all but 8 are green marbles r g 4 3 all but 4 are blue marbles.
There are 73 marbles in the jar.
The ratio of red marbles to blue marbles in a jar is 3 5.
Let the number of blue marbles be x.
The results of the experiment are recorded in the table.
You need to place all the marbles into the jars such that when you blindly pick one marble out of one jar you maximize the chances that it will be red.
There are 19 more marbles other than the green marbles.
You have two jars 50 red marbles and 50 blue marbles.
There are 3 marbles in a jar a red a blue and a yellow one.
