A probability model must satisfy which of the following? A) The probability of any event must be a number between 0 and 1, inclusive. B) The sum of all the probabilities of all outcomes in the sample space must be exactly 1. C) The probability of an event is the sum of the outcomes in the sample space that make up the event. D) All of the above.
