There Are 9 Marbles

You have a balance that has 2.

There are 9 marbles.

Find p number is. There are still 6 green marbles and 9 red ones. The marbles are all uniform in size appearance and shape. A marble is drawn at random and after recording its color the marble is returned in the box.

If 9 marbles put them in 3 groups so each group has 3 marbles so only one group would have different weight than the other two group since there s only 1 marble is different than the others. 9 blue marbles 8 green marbles 4 red marbles 8 white marbles and 6 yellow marbles. All you have is a scale and the marbles. A number cube with the numbers 1 through 6 is rolled.

2 a company has determined that 2 of the pudding cups it produces are defective in some way. 3 you are allowed to use set the scale twice in total. Write a problem where two marbles are selected at random without replacement and the probability is 1 6. The remaining marble is slightly heavier than the others.

There are 7 green 4 blue and 9 marbles in a box. There are 8 marbles that weigh 1 ounce each and 1 marble that weighs 1 1 ounces. Find the probability that the marble is blue or even numbered. 4 25 first we have the probability of drawing a green marble as 6 out of 6 9 which is 6 15.

1 you have 9 marbles as seen. So when comparing two groups of marbles there can be two outcomes 1. A marble is drawn at random from the jar. 4 each bucket has enough room for multiple marbles.

You don t know which is which. Now we already know that one of the marbles is heavier than the rest. Another marble is then drawn. At this moment the bag becomes the same as it is before a green marble is drawn i e.

2 8 of them are exactly the same weight. Math 10 points 1 there are 9 marbles representing 3 different colors. Write the probability as a fraction in simplest form a decimal and a percent. What is the fewest number of measurements you can make to figure out which is the light marble.

If we are too draw another green marble the same probability 6 15 will be resulted. There are 35 marbles in a bag. A 4 31 0 129 12 9 b 4 35 0 114 11 4 c 1 7 0 143 14 3 d 3 35 0 086 8 6 2. In other words you get to take 2 measurements or comparisons here.

There are two variants of the same question the easier of the two has been stated here. After that we replace the green marble into the bag. A jar contains 9 red marbles numbered 1 to 9 and 7 blue marbles numbered 1 to 7. There are 9 marbles 1 lighter than the rest.
