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.
When a jar contains 5 white marbles 3 blue marbles and 2 green marbles and if one marble is drawn at random then what is the probability that it will be blue?
There is a probability of 3 that it will be blue.
What is the probability that at least one marble is white if a bag has 3 green and 3 white marbles four marbles are selected at the same time?
The probability is 100%.There's no way to take four marbles out of this bag without at least one of them being white.
If there are 14 white marbles and 28 red marbles what is the probability that you would pick a white marble?
14/42. You have to add the amount of marbles and then put the probabilityof answers you're looking for. Ex: 14 white marbles 28 red marbles 14+28=42 ?/42 your looking for the probability of white marbles, so you put in the amount of white marbles on the fraction. =14/42
In a bag there are 100 marbles 10 red 20 white 30 blue and 40 green If 1 marble is drawn from the bag what is the probability that the marble will NOT be red white or blue?
40% chance

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.
What are the odds in favor of choosing a white marble from a bag containing 3 black marbles 4 green marbles and 6 white marbles?
The probability of drawing a white marble is .46
A bag contains 4red marbles 2 white marbles a marble is selected kept out the bag and then another marble is selected what is the probability of selecting a red marble and then white marble?
2/6
If a box contains 4 red marbles seven white and 5 blue and two marbles are drawn one at a time with replacement What is the probability that both marbles are white?
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.
What is the probability of drawing a marble that is not white?
It depends on how many marbles of each colour you have....
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?
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.
When a jar contains 5 white marbles 3 blue marbles and 2 green marbles and if one marble is drawn at random then what is the probability that it will be blue?
There is a probability of 3 that it will be blue.
What is the probability of picking a blue marble from a bag of 4 red marbles 6 blue marbles and 1 white marble?
11 marbles total and 6 are blue so probability is 6/11
A bag that has 7 greens marbles 3 blue marbles and 12 white marbles what is the probability of selecting a white marble on each of the three tries if the marble is placed back after each pick?
12 white marbles from (7+3+12) = 22 marblesChance of a white marble on first pick = 12/22 = 6/11.Chance of a white marble on second and third picks are the same, as the marble is replaced.So, the chance of a white marble three times is 6/11 * 6/11 * 6/11 = 216/1331 = approximately 16.23%
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%
A bag contains 6 purple and 7 white marbles two marbles are drawn at random one marble is drawn and not replaced what is the probability that the fist marble is white and the second is purple?
2/13
