Which sampling method would best help predict thubube outcome when selecting a marble from a jar that contains 30 red marbles and 20 green marbles?
select a marble from the jar, return it , and record times
What is the probabilityof choosing a green marble from a jar containing 5 red 6 green and 4 blue marbles?
The probability of choosing a green marble from this jar would be 6/15. You get this answer by adding up the sum of all the marbles.
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
What is the probability that if you draw 5 marbles from the jar without replacement 3 are red?
That depends on how many marbles are in the jar, and what colours they are. You could have 999,997 black marbles and 3 red ones, which would make the chance of drawing one red marble, quite literally, one in one million. As an interesting aside, as the number of non-red marbles grows, the probability of drawing a red one gets infinitely closer to (but never reaches) zero, assuming there is at least one red marble. This is an example of something from calculus, which becomes quite useful in thinking about some kinds of things. Please note that WikiAnswers is not here to do your homework for you. If this question is from work you have been assigned by a teacher or professor, I suggest you do the work yourself instead, which will help to increase your understanding of the subject matter and help you to become more familiar with it.
A large bag of marbles contains 57 blue marbles and 74 red marbles and 69 yellow marbles What percent of the marbles are red?
Use this formula - 100 * red / (blue+red+yellow).
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
There are 9 red and 6 blue marbles in a jar If you draw red marbles from the jar 7 times what is the experimental probability of drawing a red marble?
The answer is dependent on whether of not you replace the marbles in the jar. If you do, the probability of drawing a red marble is 9 in 15 or 60%, every time. If you do not replace the marbles, the probability of drawing a red marble is 2 in 8 or 25%.
What is the chance of a red marble being drawn at random from a jar in which there are 50 red marbles and 50 yellow marbles?
It is 50/100 = 1/2
Suppose a jar contains 3 red marbles and 2 white marbles if a marble is drawn at random what is the probability it is red?
3/5 or .6
A marble is selected from a random jar containing 3 red marbles 4 yellow marbles and 2 marbles what are the odds in favor of selecting a red marble?
The probability of selecting a red marble is 3/9
A jar has 6 marbles 1 blue 1 white 1 green 1 yellow 1 red 1 black If 5 marbles are removed at random what is the probability that the green marble was removed?
5/6
Which sampling method would best help predict thubube outcome when selecting a marble from a jar that contains 30 red marbles and 20 green marbles?
select a marble from the jar, return it , and record times
What is the probabilityof choosing a green marble from a jar containing 5 red 6 green and 4 blue marbles?
The probability of choosing a green marble from this jar would be 6/15. You get this answer by adding up the sum of all the marbles.
What is the probability of choosing a red marble from a jar containing 5 red 6 green and 4 blue marbles?
First, you add all the numbers together- 5+6+4=15. So the number of red marbles (5) and the total number of marbles (15)= 5/15=1/3
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
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%
What is the probability of choosing a marble that is not blue if a jar contains 4 red 7 green and 5 blue marbles?
5:16
