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 contains five green marbles and four red marbles what is the odds of in favor picking a green marble on the first selection?
There is a one in 2 chance of getting a green marble.
What is the probability of chossing 12 marbles from a jar in numercial order?
The probability of picking the #1 marble on the first draw is 1/12. If you've done that, then the probability of picking the #2 marble on the second draw is 1/11. If you've done that, then, the probability of picking the #3 marble on the third draw is 1/10. If you've done that, then, the probability of picking the #4 marble on the fourth draw is 1/11. etc. etc. So the probability of doing all of them in sequence is (1/12) x (1/11) x . . . x (1/1). That's exactly the reciprocal of (12!). According to my $1.49 calculator, your chances of success without peeking amount to about 0.00000020877 percent (rounded) Not a smart bet.
There are 4 blue marbles 1 yellow and 7 black in a bag what chance is there of picking a black?
7/12
What is a probability of an event?
Lets first start by defining some terms:Probability (P) in statistics is defined as the chance of an event occurring.Probability experiment is a chance process that leads to results called outcomes.An outcome is the result of a single trial of a probability experiment.A sample set is the set of all possible outcomes of a probability experiment.An event consists of a set of outcomes of a probability experiment. An event can be one outcome or more than one outcome. The event can be anything from flipping a coin, to rolling a die, to picking a card.The probability of any event (E) is:(# of outcomes in E) / (total # of outcomes in sample space)For example: Find the probability a die is rolled and you get a 4?We know that there are 6 possibilities when rolling a die. We can either rolled a 1, or a 2, or a 3, or a 4, or a 5, or a 6.Using the equation above:P(rolling a 4)= 1/6The event in this case is rolling a 4.
What is the probablility of picking a green marble at random from a box that contains only 11 blue marbles?
The probability of picking a green marble from a box that only contains blue marbles is zero.
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.
If you have 6 red marbles 3 yellow marbles and 5 green marbles in a bag what is the probability of picking a blue marble out?
0No blue marbles in the bag.
What is the probability of picking a red marble and then a blue marble?
None, if all the marbles that you have are yellow!
There is a bag of marbles 10 are red 15 are purple and 25 are yellow what is the probability of picking a purple marble?
3/10 or 0.3 is the probability of picking a purple marble.
A bag contains 3 blue marbles 7 red marbles and 5 yellow marbles If Joe picks 1 marble from the bag at random what is the probability that it will be blue?
1 in 15 chances that the marble will be blue, because there are 15 marbles all together in a bag, and you are only picking one out of it.
What s the probability of not picking a green marble in a jar that contains 5 red 6 green and 4 blue?
The answer depends on how many marbles are picked and on whether or not they are returned to the jar before picking the next one. Since you have not bothered to provide any information on either of these aspects, I cannot provide a more useful answer.
A bag has 7 blue marbles and 8 purple marbles.What is the probability of picking a blue marble then a purple marble without replacing?
7/15 for blue marbles and 8/14 for the purple marbles this is dependent probability
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 contains 4 red marbles and 5 blue marbles If two marbles are chosen at random what is the probability of getting two red marbles?
1/6Because:There is a 4 in 9 chance of picking a red ball the first time and 3 in 8 chance of picking a red ball the second time. The chance of picking two reds as the first two balls is 4/9 x 3/8 or 12/72 or 1/6
A bag contains 5 green marbles 3 yellow and 2 red marbles. What is the probability of picking three green marbles from the bag without replacement?
To find the answer to probability, first add all the things together (5+3+2=10), then, find the number of things you will be taking from the group of things (3), and put together as a fraction (3/10). So the final answer is 3/10, which is unlikely. :D
42 red marbles 17 green marbles 27 blue marbles what is the experimental probability of picking a green marble?
if you pick one marble at random, the odds are 17/(42+17+27) or 17/86 or about 20%
