Explain how a cardinal number formula can be derived for the case where three sets occur. Specifically, give a formula relating n(A UBUC) to n(A), n(B), n(C), n(An B), n(An C), n(B n C), and n(A n B nC). Illustrate with a Venn diagram. Extend the procedure for cardinality from three sets to two sets. Which of the following formulas does this give? A. n(AUBU C) = n(A) + n(B) + n(C) - n(An B)-n(An C)- n(B nC) B. n(AUB UC) = n(A) + n(B) + n(C) n(An B)-n(An C)- n(B nC) + n(An B nC) C. n(AUB UC) = n(A) + n(B) + n(C) - n(An B)- n(An C)- n(B nC) - n(AnBnC) D. n(A UBUC) = n(A) + n(B) + n(C)
