To solve for $P(A \cup B)$, we use the formula for the probability of the union of two events $A$ and $B$:

$P(A \cup B) = P(A) + P(B) - P(A \cap B)$

However, before proceeding, we need more specific information from the Venn diagram, such as the values of $P(A)$, $P(B)$, and $P(A \cap B)$. If you have the diagram or these probabilities, could you provide them?

Would you like to upload the diagram for further clarification?

Here are 5 related questions to explore this further:

1. How do you compute the probability of the intersection $P(A \cap B)$?
2. What is the difference between $P(A \cup B)$ and $P(A \cap B)$?
3. If $P(A)$ and $P(B)$ are mutually exclusive, what is $P(A \cup B)$?
4. How can Venn diagrams help visualize probability problems?
5. How do conditional probabilities relate to Venn diagrams?

Tip: When dealing with Venn diagrams in probability, always consider if the events overlap (i.e., their intersection) to avoid double counting.
