Answer: Hope this helps!
Step-by-step explanation:
If events A and B are mutually exclusive, it means that they cannot occur at the same time. Therefore, the probability of either event A or event B occurring (P(A or B)) is equal to the sum of their individual probabilities.
Given:
P(A) = 0.1
P(B) = 0.8
Since events A and B are mutually exclusive:
P(A or B) = P(A) + P(B)
Substituting the given probabilities:
P(A or B) = 0.1 + 0.8
P(A or B) = 0.9
So, the probability of event A or event B occurring is 0.9.
