Question

According to the Venn Diagram below and given that P(A) = .45 as well as

Answer 1

Answer:  C) 0.75

Work Shown:

$P(A \cup B) = P(A) + P(B) - P(A \cap B)\\\\P(A \cup B) = 0.45 + 0.4 - 0.10\\\\P(A \cup B) = 0.75$

The region between circles A and B, or the overlapping region, is known as the intersection of the two sets. This is denote by $A \cap B$
