There are 13 marbles in total. The order is specified.
P(1st is white and the 2ndis purple) = (7/13)(6/12) = (7/13)(1/2) = 7/26.
A bag contains 6 purple marbles and 7 white marbles Two marbles are drawn at random One marble is drawn and not replaced Then a second marble is drawn What is the probability that the first marble?
How big is the marble? If it is 12" across, you'll fit one in there.
Composite marble is made by mixing at least 90 percent of natural marble chips or powder with polyester resin and color pigment. It is generally formed in blocks with the size of around 120x300x85cm and is cut and polished as of cutting natural marble. The original idea of inventing composite marble is to eliminate the downsides of natural marble such as inconsistency in color, porosity, color limitation,uncontrollable veining, etc. Composite marble has gained popularity among designers for its compatibility with today's modernity.

The average speed is exactly 30 meters per 6 seconds. Expressed in some other units . . . -- 300 meters/minute -- 18 kilometers/hour -- 5 meters/second -- 0.005 millimeters/microsecond

Probability of drawing a red marble = 4/16 = 1/4 Probability of drawing not a red marble = 1 - 1/4 = 3/4
There is a probability of 3 that it will be blue.
The probability of picking a green marble from a box that only contains blue marbles is zero.
2/6
probability of pulling out a purple marble = 20/85probability of NOT pulling out a purple marble = 1 - 20/85 = 65/85 = 13/17
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.
Since the box contains 16 marbles, seven of them white, then the probability of drawing one white marble is 7/16. If you replace the marble and draw again, the probability of drawing another white marble is still 7/16. The net probability of drawing two white marbles, while replacing the first, is 49/256.
We will assume that the bag contains 11 marbles (this is not a trick question!), so 4 are blue and 7 are not blue, so the probability of a color other than blue is 7/11.
80% chance, Or 40/50
it would be red because the probability is 5/9
