An assignment of probability must obey which of the following?

• The probability of any event must be a number between 0 and 1, inclusive.

• The sum of all the probabilities of all outcomes in the sample space must be exactly 1.

• The probability of an event is the sum of the outcomes in the sample space which make up the event.

• All of these reasons
