There are 9 marbles.

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

There are 9 marbles 1 lighter than the rest. A jar contains 9 red marbles numbered 1 to 9 and 7 blue marbles numbered 1 to 7. You don t know which is which. 2 a company has determined that 2 of the pudding cups it produces are defective in some way.

There are two variants of the same question the easier of the two has been stated here. What is the fewest number of measurements you can make to figure out which is the light marble. After that we replace the green marble into the bag. Find p number is.

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. 3 you are allowed to use set the scale twice in total. A marble is drawn at random and after recording its color the marble is returned in the box. All you have is a scale and the marbles.

So when comparing two groups of marbles there can be two outcomes 1. 4 each bucket has enough room for multiple marbles. In other words you get to take 2 measurements or comparisons here. A marble is drawn at random from the jar.

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. Write the probability as a fraction in simplest form a decimal and a percent. Write a problem where two marbles are selected at random without replacement and the probability is 1 6. 9 blue marbles 8 green marbles 4 red marbles 8 white marbles and 6 yellow marbles.

So take the two groups aside and you left with 3 marbles and weigh them again and you find the result. The remaining marble is slightly heavier than the others. A number cube with the numbers 1 through 6 is rolled. The marbles are all uniform in size appearance and shape.

There are still 6 green marbles and 9 red ones. Another marble is then drawn. 2 8 of them are exactly the same weight. Now we already know that one of the marbles is heavier than the rest.

If we are too draw another green marble the same probability 6 15 will be resulted. There are 35 marbles in a bag. At this moment the bag becomes the same as it is before a green marble is drawn i e. Math 10 points 1 there are 9 marbles representing 3 different colors.
