In this section, we want to consider the problem of how to count the number of ways of distributing k balls into n boxes, under various conditions. The conditions that are generally imposed are the following: 1) The balls can be either distinguishable or indistinguishable. 2) The boxes can be .I need to find a formula for the total number of ways to distribute $N$ indistinguishable balls into $k$ distinguishable boxes of size $S\leq N$ (the cases with empty boxes are allowed). So I .
I found an explanation which explained it like this: Let the balls be ∘ ∘. To find out how the balls are distributed in the boxes we use N − 1 N − 1 "|". That way we have M + N − 1 M + N − 1 .

15 distinguishable balls into five distinguishable boxes, Assume there is no restriction on which box gets one ball, which box gets two balls, etc. 0 How many ways are there to distribute 6 distinguishable objects into 4 indistinguishable boxes so that each of the boxes contain at least 1 . You run into a problem here. As I commented, (and as a subsequent answer has explained in detail), the formula you write is valid only for distinguishable balls in distinguishable boxes.. Further, if the balls are treated as indistinguishable, the unrestricted number of ways can be found out by stars and bars as $\binom{n+m-1}{n} = D\;\;(say)$ ways, but these are not .
Let's look at your example $ boxes and $ balls. Suppose your ball distribution is: $$\text{box}_1 = 2, \text{box}_2 = 0, \text{box}_3 = 1, \text{box}_4 = 0$$ You can encode this configuration in the sequence 0010$ with the $'s representing the balls and $\begingroup$ Understand what you try to remove from all possible cases. However, I thought the opposite cases to 'no box can contain more than one ball from same indistinguishable color group and no empty boxes' should be 'at least one box contains more than one ball of the color AND there is at least one empty box'.'s$ the transition from one box to the other.
Find step-by-step Discrete math solutions and your answer to the following textbook question: How many ways are there to distribute 12 indistinguishable balls into six distinguishable bins?. Scheduled maintenance: December 24, 2023 from 05:00 AM to 06:00 AM In how many ways can you distribute 12 indistinguishable objects into 3 different boxes. where box 1 can have at most 5 objects, box 2 can have at most 6 objects and box 3 can have at most 4 objects. If we were just talking about the question without the inequalities I would use the formula C(n+r-1,n-1).
15 distinguishable balls into five distinguishable boxes, Assume there is no restriction on which box gets one ball, which box gets two balls, etc. 2 How many ways are there to place 7 distinct balls into 3 distinct boxes?
The identical nature of the balls tells us it can be done in only 1 way. So we are left with the task of filling 10 identical balls in 5 boxes. The answer 5^20 is not right for identical balls, think of a less severe situation with 4 balls and 2 boxes, the problem is essentially asking in how many ways can you put the 4 balls in two different .Find step-by-step Discrete math solutions and your answer to the following textbook question: How many ways are there to distribute 12 distinguishable objects into six distinguishable boxes so that two objects are placed in each box?. First, count the number of ways to distribute $ balls into $ boxes so that no box is empty: Include the number of ways to distribute $ balls into at most $\color\red4$ boxes, which is $\binom{4}{\color\red4}\cdot\color\red4^7$

Now we have a box with a ball and a box without a ball, which makes the boxes distinguishable and n-1 balls remaining to be distributed into those boxes. Let the remaining balls choose any of the two boxes: ^{n-1}$. Hence, my answer is: ${n \choose 1}\cdot 2^{n-1}$.
¥ Distrib uting objects into boxes: Some counting problems can be modeled as enumerating the w ays obje cts can be placed into box es, where objects and box es may be distinguishable or indistinguishable. Ð Distinguishable objects and distinguishable boxes: The number of w ays to distrib ute n distinguishable Suppose you had n indistinguishable balls and k distinguishable boxes. Enumerate the ways of distributing the balls into boxes. Some boxes may be empty. We can represent each distribution in the form of n stars and k − 1 vertical lines. The stars represent balls, and the vertical lines divide the balls into boxes. For [.]
