Billiards Ball On The Table
Introduction
Imagine a scenario where you have two tables, one red and one white, each containing a set of billiard balls of different colors. Initially, the red table is filled with 111 billiard balls, while the white table remains empty. The objective is to perform a series of operations on the tables, alternating between them, to achieve a specific outcome. This problem is a classic example of a combinatorial puzzle, requiring a deep understanding of mathematical concepts and logical reasoning.
The Rules of the Game
The rules of the game are as follows:
- The red table initially contains 111 billiard balls of different colors.
- The white table is empty.
- Operations are performed alternately on the tables.
- In each operation, a ball is removed from the red table and placed on the white table.
- The removed ball is not replaced on the red table.
- The game continues until all balls have been transferred to the white table.
Combinatorial Analysis
To solve this problem, we need to analyze the combinatorial aspects of the game. Let's consider the number of ways to choose a ball from the red table in each operation. Since there are 111 balls of different colors, the number of ways to choose a ball is 111.
However, as the game progresses, the number of balls remaining on the red table decreases. In the first operation, there are 111 balls to choose from. In the second operation, there are 110 balls remaining on the red table, and so on. This creates a sequence of numbers, where each term is one less than the previous term.
Sequences and Combinations
The sequence of numbers representing the number of balls remaining on the red table is a classic example of an arithmetic sequence. An arithmetic sequence is a sequence of numbers in which the difference between any two consecutive terms is constant.
In this case, the common difference is -1, since each term is one less than the previous term. The sequence can be represented as:
111, 110, 109, ..., 1
This sequence has 111 terms, and each term represents the number of balls remaining on the red table after each operation.
Permutations and Combinations
To find the total number of ways to transfer the balls from the red table to the white table, we need to consider the permutations and combinations of the balls.
Since each ball is unique, the order in which they are transferred matters. Therefore, we need to calculate the number of permutations of the 111 balls.
However, since the balls are not replaced on the red table, the number of permutations is not simply 111!. We need to account for the fact that the balls are being transferred one by one, and the order in which they are transferred matters.
The Formula for Permutations
The formula for permutations is given by:
P(n) = n!
where n is the number of items being permuted.
In this case, n = 111, since there are 111 balls being transferred.
Calculating the Permutations
Using the formula for permutations, we can calculate the total number of ways to transfer the balls from the red table to the white table:
P(111) = 111!
This is a very large number, and it represents the total number of ways to transfer the balls from the red table to the white table.
Conclusion
In conclusion, the billiards ball problem is a classic example of a combinatorial puzzle. By analyzing the sequence of numbers representing the number of balls remaining on the red table, we can calculate the total number of ways to transfer the balls from the red table to the white table.
The formula for permutations provides a powerful tool for solving this problem, and it highlights the importance of combinatorial analysis in solving complex problems.
The Final Answer
The final answer to the billiards ball problem is:
P(111) = 111!
This represents the total number of ways to transfer the balls from the red table to the white table.
