Answer:
A. [tex]P(A\cup B)=0.55[/tex]
Step-by-step explanation:
From the Venn diagram,
[tex]P(A) = 0.3, P(B) = 0.35, and P(A\cap B) = 0.10[/tex]
Therefore, from the rule of Addition of probabilities,
[tex]P(A\cup B )=P(A)+P(B)-P(A\cap B)\\P(A\cup B )=0.3+0.35-0.10\\P(A\cup B )=0.55[/tex]
Therefore, option A is correct.
