Question

the venn diagram here shows the cardinality of each set. use this to find the cardinality of the given set.
n \left(a\cup b^{c}\
ight) = \square

Explanation:

Step1: Define $B^c$ (complement of B)

$B^c$ includes all elements not in set B: 8, 7, 4, 13, 4

Step2: Define set A

Set A includes: 8, 7, 1, 4

Step3: Find $A \cup B^c$ (union of sets)

Combine unique elements from both sets: 8, 7, 4, 13, 4, 1

Step4: Calculate cardinality

Sum the elements: $8 + 7 + 4 + 13 + 4 + 1$

Answer:
