Answer:
c. 0.80
Step-by-step explanation:
If two events A and B are mutually exclusive they cannot occur simultaneously, but they can occur independently and so their individual probabilities can be added.
[tex]P(A \cap B) = 0\\P(A \cup B) = P(A) + P(B)[/tex]
Therefore: P(A ∪ B) is:
[tex]P(A \cup B) = 0.3+0.5\\P(A \cup B) = 0.8[/tex]
Thus, the answer is c. 080
