basic probability\nwhich option below represents the shaded area of this venn diagram?\na ∪ b\na ∩ b\na^c\nb^c

Explanation:

Step1: Recall set - notation meanings

$A\cup B$ represents the union of sets A and B (all elements in A or B). $A\cap B$ represents the intersection of sets A and B (all elements in both A and B). $A^{c}$ represents the complement of set A (all elements not in A) and $B^{c}$ represents the complement of set B (all elements not in B).

Step2: Analyze the Venn - diagram

If the entire rectangle is the universal set $\xi$, and the shaded area is everything that is not in set A.

Answer:

$A^{c}$
