Question

The sum of the probabilities of all possible outcomes of an event is A. less than 1​

Answer 1

Step-by-step explanation:

Probability is a number that can be assigned to outcomes and events. It always is greater than or equal to zero, and less than or equal to one. The sum of the probabilities of all outcomes must equal 1 . ... The probability that an event does not occur is 1 minus the probability that the event does occur.

Answer 2

Answer:

It always is greater than or equal to zero, and less than or equal to one. The sum of the probabilities of all outcomes must equal 1 . ... Two events A and B are independent if knowing that one occurs does not change the probability that the other occurs.
