Solution

To approach this Venn diagram problem, we'll break down the given information and figure out how the sets $A$ , $B$ , and $C$ intersect. Here’s a step-by-step guide:

Given Information:

$n(U) = 9$ : The total number of elements in the universal set $U$ .
$n(A) = 1$ : The number of elements in set $A$ .
$n(B) = 9$ : The number of elements in set $B$ .
$n(C) = 0$ : The number of elements in set $C$ (i.e., set $C$ has no elements).
$n(A \cap B) = 5$ : The number of elements in both $A$ and $B$ .
$n(A \cap C) = 3$ : The number of elements in both $A$ and $C$ .
$n(B \cap C) = 3$ : The number of elements in both $B$ and $C$ .
$n(A \cap B \cap C) = 2$ : The number of elements common to $A$ , $B$ , and $C$ .

Step-by-Step Solution:

Observations:

Set $C$ has zero elements: This means that $C$ $C$ is an empty set.
- This contradicts the values for $n(A \cap C) = 3$ , $n(B \cap C) = 3$ , and $n(A \cap B \cap C) = 2$ , since $C$ should not contain any elements.

Conclusion:

The conditions provided are impossible to meet because the number of elements in $C$ is zero, but the intersections involving $C$ are non-zero. Thus, there’s a contradiction in the problem's setup.

Answer Choices:

B is the correct choice:
- It is impossible to meet the conditions because there are only 1 element in set $A$ , but there are 3 elements in set $A$ that are also in set $B$ or $C$ , which creates a contradiction.

Here are five additional related questions to consider:

What happens when a set is empty in a Venn diagram?
How do you determine if conditions for a Venn diagram are possible?
How does the cardinality of a universal set affect the problem?

Tip: Always double-check if the given set sizes are consistent with their intersections before calculating region values in Venn diagrams.
