Is Transitivity Applicable in Proving Subset Relations Among Sets A, B, and C?

In summary, the problem with basic sets proof is that it assumes all elements in a set are distinct, leading to potentially inaccurate or invalid conclusions. This can have a significant impact on scientific research, as it can undermine the validity of studies. However, the problem can be overcome by using alternative methods such as fuzzy set theory and being mindful of definitions and assumptions. Real-life examples of this issue have been seen in legal cases, where incorrect verdicts can be reached due to this assumption. To avoid falling into this trap, scientists should carefully consider their use of set theory and utilize alternative methods when appropriate, as well as seeking peer review and critical analysis of their research.

Hello I'm having problems with actually proving this with some mathematics.
Let A, B, C be sets. Prove that if A is a subset of B and B is a subset of C then A is a subset of C.
Thanks.

hi adriang! :smile:

always start proofs of this sort with "if a is in A, …" :wink:

[tex]A \subseteq B[/tex] means if [tex]x\in A[/tex] then [tex]x\in B[/tex] for all [tex]x\in A[/tex].
 

FAQ: Is Transitivity Applicable in Proving Subset Relations Among Sets A, B, and C?

What is the problem with basic sets proof?

The problem with basic sets proof is that it relies on the assumption that all elements in a set are distinct, which may not always be true. This can lead to inaccurate or invalid conclusions.

How does the problem with basic sets proof affect scientific research?

The problem with basic sets proof can have a significant impact on scientific research, as it can lead to incorrect conclusions being drawn and potentially invalidating the entire study. It is important for scientists to be aware of this issue and approach set theory with caution.

Can the problem with basic sets proof be overcome?

Yes, there are ways to address the problem with basic sets proof. One approach is to use alternative methods, such as fuzzy set theory, which allows for elements to have varying degrees of membership in a set. Additionally, careful attention to the definitions and assumptions used in set theory can help to mitigate this issue.

Are there any real-life examples of the problem with basic sets proof?

Yes, there have been instances where the problem with basic sets proof has affected real-life situations. For example, in legal cases where set theory is used to determine guilt or innocence, the assumption of distinct elements can lead to incorrect verdicts.

How can scientists avoid falling into the trap of the problem with basic sets proof?

To avoid the problem with basic sets proof, scientists should carefully consider the definitions and assumptions used in their research. They should also be aware of alternative methods, such as fuzzy set theory, and use them when appropriate. Additionally, peer review and critical analysis of research can help to identify and address any issues related to set theory assumptions.
