A marble is drawn at random first from a jar containing four black and four white marbles and then from a jar containing six black and two white marbles What is the probability of drawing two black?
It is (4/8)*(6/8) = 3/8
If there are 3 black marbles 2 white marbles and 1 red marble what is the probability of selecting a black marble?
3/6 or 1/2 or 50%
Suppose there are three white marbles and three black marbles in a bag and you want to remove two marbles What is the probability that you will select a white marble and then a black marble Express?
3/6 * 3/5 = 6/30 or 1/5 so you have a 20% chance of pulling a white and then black marble.
If you have 50 black marbles and 50 white marbles in a bag at most how many times would you have to draw out a marble to get two the same colour?
The maximum number of marbles you have to draw is three. 1) Draw a marble. It is either white or black. 2) Draw a second marble. If it is the same colour as the first marble, we are done after two draws. 3) Otherwise, the drawn marbles have different colours. Draw a third marble. No matter what you draw next, you must have two marbles of the same colour.
A jar contains 40 red marbles and 10 black marbles If you take a random sample of one marble from this jar. What is the probability that the marble will be red?
80% chance, Or 40/50

A bag contains 4 red marbles and 3 black marbles You dram one marble look at it and put it back Then you draw one marble again What are your chances of getting 2 black marbles?
3/7*3/7= 9/49
There are twelve marbles in a bag one black two orangefour greenfive yellow what is the probilty of choosing green or yellow?
The answer is 9/12 or 3/4 probilty that you will pick a green or yellow marble.
What is the equation used to determine probability?
Number of possibilities for one category / Total of all possibilities. For example, if I had a bag of marbles where there are three white marbles and two black marbles. The probability of pulling out a white marble is how many white marbles are in the bag which is: three. But the total of things you can draw out of the bag can either be one of the three white marbles or one of the two black marbles. 3 white marbles+ 2 Black marbles= five marbles. Possibility is 3/5 for drawing a white marble.
A jar contains 40 red marbles and 10 black marbles If you take a random sample of one marble from this jar. What is the probability that the marble will be red?
80% chance, Or 40/50
What is marble's streak?
Marbles do have streaks from impurities durring metamorphisis, and they are of various colors
There are 3 red marbles 7 blue marbles 6 green marbles and 4 black marbles in a bag a marble is randomly selected from the bag the number one fifth represents the probability of selecting what color?
a black one
A bag contains 3 red marbles 5 blue marbles 8 yellow marbles and 4 black marbles what is the theoretical probability of randomly picking each color marble?
The theoretical probability of randomly picking each color marble is the number of color marbles you have for each color, divided by the total number of marbles. For example, the probability of selecting a red marble is 3/20.
What is the chance of people all getting a blue marble out of a box with 5 blue marbles and 5 black marbles?
