Work Shown:
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.8 + 0.55 - 0.35
P(A or B) = 1.35 - 0.35
P(A or B) = 1
A probability of 1 means there is 100% certainty the event happens. This must mean that there are only possible outcomes are: either event A happens, or B happens, or possibly both A and B happen simultaneously.
