There Are 9 Marbles

A marble is drawn at random and after recording its color the marble is returned in the box.

There are 9 marbles.

A marble is drawn at random from the jar. 4 each bucket has enough room for multiple marbles. 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. 2 8 of them are exactly the same weight.

Write a problem where two marbles are selected at random without replacement and the probability is 1 6. After that we replace the green marble into the bag. So take the two groups aside and you left with 3 marbles and weigh them again and you find the result. Write the probability as a fraction in simplest form a decimal and a percent.

Find the probability that the marble is blue or even numbered. 2 a company has determined that 2 of the pudding cups it produces are defective in some way. A number cube with the numbers 1 through 6 is rolled. 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.

Find p number is. You have a balance that has 2. What is the fewest number of measurements you can make to figure out which is the light marble. There are 35 marbles in a bag.

In other words you get to take 2 measurements or comparisons here. There are 8 marbles that weigh 1 ounce each and 1 marble that weighs 1 1 ounces. 4 25 first we have the probability of drawing a green marble as 6 out of 6 9 which is 6 15. The marbles are all uniform in size appearance and shape.

So when comparing two groups of marbles there can be two outcomes 1. 3 you are allowed to use set the scale twice in total. There are 7 green 4 blue and 9 marbles in a box. All you have is a scale and the marbles.

A jar contains 9 red marbles numbered 1 to 9 and 7 blue marbles numbered 1 to 7. There are still 6 green marbles and 9 red ones. If we are too draw another green marble the same probability 6 15 will be resulted. Anonym s answer was correct.

Now we already know that one of the marbles is heavier than the rest. One of them weig. You don t know which is which. Math 10 points 1 there are 9 marbles representing 3 different colors.

There are two variants of the same question the easier of the two has been stated here. There are 9 marbles 1 lighter than the rest. Another marble is then drawn. 1 you have 9 marbles as seen.
