What is the sum of the probabilities of all of the outcomes in a sample space?
one (1)
What is the sum of all probabilities?
Sum of all probabilities is 1.
Can the sum of 2 probabilities be greater than 1?
Yes but it is not possible to attach any interpretation to that. The addition of probabilities makes sense only if they are mutually exclusive outcomes of the same trial. If they are, then their sum cannot be greater than 1.
What are two requirements for a discrete probability distribution?
Not sure about only two requirements. I would say all of the following:there is a finite (or countably infinite) number of mutually exclusive outcomes possible,the probability of each outcome is a number between 0 and 1,the sum of the probabilities over all possible outcomes is 1.The Poisson distribution, for example, is countably infinite.
What re the three criteria needed for something to be a probability distribution?
A probability distribution must have a well defined domain - that is, the set of possible outcomes.For each possible outcome, there must be a non-negative value associated - the probability of that outcome.The sum of the probabilities, over all possible outcomes, must be 1.
What are some characteristics of probability?
It is a real number. It cannot be negative. The sum of the probabilities of all possible outcomes of a discrete variable is 1. Similarly, the integral of the probabilities over the whole range of possible outcomes of a continuous variable is 1.
What is the sum of the probabilities of all outcomes in a sample space?
1

What is the sum of the probabilities for each situation?
The sum of the probabilities of all possible results is one (1). That'sjust another way of saying that one of those results musthappen.
What are allowable probabilities?
A probability must be a real number in the interval [0, 1]. The sum (or integral) of the probabilities over all possible values must be 1.

The sum of all probabilities equals what?
One.
How many possible outcomes sum of dots are there if you throw the two dice on the board?
The sum can be any number from 2 to 12.That's 11 possible outcomes.
