use the accompanying venn diagram, which shows the cardinality of each region, to answer the question below. how many elements belong to set b or set c, but not set a? there are elements that belong to set b or set c, but not set a.
Answer
Explanation:
Step1: Identify relevant regions
Regions in $B\cup C$ and not in $A$ are $7$, $4$, $9$, $3$.
Step2: Calculate total
Add the cardinalities of these regions: $7 + 4+9 + 3$. $7+4+9 + 3=23$.
Answer:
$23$
