If A bag contains 3 orange 5 black and 2 white marbles Two marbles are drawn but the first marble is not replaced Find P white then black?
Bag with 10 marbles: 3 orange, 5 black, 2 white.
Rephrasing the question.
If a marble is drawn from the bag, then returned to the bag, and a second marble
is drawn, what is the probability that the first marble turns out white and the second
marble black ?
The probability for a marble to come out white from the bag is:
P(W) = 2/10 = 1/5
The probability for a marble to come out black from the bag is:
P(B) = 5/10 = 1/2
The probability for a marble to come out white, put back in the bag and then take again a marble for a second time and turns out to be black is:
P(B2|W1) = (1/5)∙(1/2) = 1/10 = 0.10 = 10 %

A bag contains 6 orange 7 green and 8 yellow marbles Find the probability of picking 3 yellow marbles if each marble is returned to the bag before the next marble is picked?
Well, honey, if you're reaching into that bag three times and each time you're pulling out a yellow marble and then putting it back in, the probability of picking a yellow marble each time is 8/21. Multiply that by itself three times because you're picking three marbles, and you get a probability of 512/9261. So, good luck with those yellow marbles, darlin'!
A bag contains 8 marbles 4 are blue 3 are green and one is orange you draw out one marble and then another without replacing the first marble Find the probability of drawing 2 blue marbles?
Probability of drawing a blue marble first is 4 in 8 (or 50%) Probability of drawing a blue marble second is 3 in 7 (or 42.85714%) Probablility of drawing blue then blue is the two above multiplied 0.5 * 0.4285714 Which is 0.212142407 or 21% or One in Five.
In a bag of marbles there were 4 red 3 blue 5 green 3 black and 5 orange what are your chances of taking a blue marble out of the bag?
Ok so first you have 20 marbles in all. Since you have 3 blue marbles the fraction would be 3/20 which you can't reduce. To find in decimal form just punch in 3/20!! -Welcome
How do play the decoder in 39 clues?
In decoder for the 39 clues, you start out with several different colored marbles in the bottom. Depending on what level you are on, you will always get orange and green marbles. The goal of the game is to match the code at the end of the board (hidden). However, on the right of the board are 4 empty holes. If you press the solve button on the board, you will get either a white colored marble, black marble, or none at all. White colored marbles mean that you have a right color, but in the wrong position. Black means that you have the right colored marble and it is in the correct position. If none appears at all in a hole, that means you have the wrong colored marble and wrong position. Good Luck Cahill!
