the probability of an event is 0.001. Which of the following best describes the event? A The event will never occur. B There is a small chance that the event will occur. C The event is likely to occur. D The event will definitely occur.
B. There is a small chance that the event will occur. C and D are definitely wrong since 0.001 is equal to 0.1%, that's not even 1%. But even though it's small, that doesn't mean it's impossible, just highly unlikely. So the answer is B.
