An opaque jar contains 6red marbles.
For the second marble the probability of getting a red would be 12 47.
Pulling out 2 marbles is the same as to taking out one marble and then taking out another marble form whats remaining in the jar.
The following exercise refers to the experiment of picking two marbles from the jar without replacing the first one.
A glass jar contains 6 red 5 green 4 blue and 5 yellow marbles of same size.
The probability of getting one green and one red marble is.
Suppose an opaque jar contains 4 red marbles and 10 green marbles.
What is the probability of getting a green marble first and a red marble second.
Suppose an opaque jar contains 7 red marbles and 10 green marbles.
For the first part the probability of getting a red marble we have 12 total marbles and 2 are red.
10 15 5 14 50 210 5 21 2.
I experiment picking 2 marbles from the jar without replacing the first one.
Hari takes out a marble from the jar at random.
A marble is drawn at random from the jar.
The probability of both happening would be 1 4 x 12 47.
Find the probability of the given.
What is the probability of getting a green marble and a red marble.
Enter your probability as a fraction.
What is the probability of getting a green marble first and a red marble second.
The second probability is.
The probability of getting a green marble first and a red marble second is.
What is the probability of getting a green marble and a red marble together.
A jar contains 2 red marbles numbered 1 to 2 and 10 blue marbles numbered 1 to 10.
Suppose an opaque jar contains 5 red marbles and 10 green marbles.
Two marbles are picked at random from the jar without replacing the first one.
Suppose an opaque jar contains 3 red marbles and 10 green marbles.
What is the probability of getting a green marble and a red marble.
What is the probability of getting a green marble and a red marble.
Suppose an opaque jar contains 3 red marbles and 10 green marbles.
For the first marble the probably of getting a red would be 12 48 which is 1 4.
Enter your probability as a fraction.
Suppose an opaque jar contains 5 red marbles and 10 green marbles.
So the chance of getting a red one is 2 12 or 1 6.
The following exercise refers to the experiment of picking two marbles from the jar without replacing the first one.
