I'm reading an introductory statistics textbook and it mentioned this:
"The probability of any outcome is the long-term relative frequency of that outcome. Probabilities are between zero and one, inclusive(that is, zero and one and all numbers between these values). P(A) = 0 means the event A can never happen. P(A) = 1 means the event A always happens"
