-aux.01 Venn diagram universal set U and sets A and B.

Click For Summary

Discussion Overview

The discussion revolves around the interpretation and calculation involving a Venn diagram with a universal set U and subsets A and B. Participants explore set operations, specifically the union and intersection of sets, and their implications in terms of probabilities.

Discussion Character

  • Mathematical reasoning

Main Points Raised

  • One participant presents the expression $$B\cap A'$$ as part of their reasoning.
  • Another participant states they have the expression $B\cup A'$ and provides a probability calculation involving this union.
  • A later post reiterates the expression $B\cup A'$ and the associated probability calculation, confirming it as correct.

Areas of Agreement / Disagreement

There appears to be agreement on the correctness of the probability calculation involving $B\cup A'$, but the overall discussion does not reach a consensus on the broader implications or interpretations of the set operations.

Contextual Notes

The discussion does not clarify the definitions of the sets A and B or the context of the universal set U, which may affect the interpretations of the expressions used.

so I have $B\cup A'$

(c)
$\displaystyle\frac{n(B\cup A')}{n(U)}=\frac{35}{100}=\frac{7}{20}$

That is correct. :D
