Answer:
c) Either A or B or both occur.
Step-by-step explanation:
Suppose that we have two events
Event A
Event B
We have that:
[tex]A = a + (A \cap B)[/tex]
In which a a happens and b does not and [tex]A \cap B[/tex] is the probability that aboth events happen
By the same logic, we have that:
[tex]B = b + (A \cap B)[/tex]
The union of events A and B is:
[tex](A \cup B) = a + b + (A \cap B)[/tex]
Which includes either one of them or both.
So the correct answer is:
c) Either A or B or both occur.
