What is the sum of the probabilities of all possible outcomes?
The sum of the probabilities of all possible outcomes is 1.
What are the requirements for probability distribution?
(1) That the probabilities lie between 0 and 1. (2) The sum of all probabilities of the distribution sum up to 1.
In the discrete probability distribution what is the sum of all probabilities?
The sum should equal to 1.
What is the sum of the probabilities of all of the outcomes in a sample space?
one (1)
What is the sum of the probabilities of each outcome multiplied by the outcome value?
expected value
What is the sum of the probabilities of all possible outcomes?
The sum of the probabilities of all possible outcomes is 1.
The sum of all probabilities equals what?
One.
What are the requirements for probability distribution?
(1) That the probabilities lie between 0 and 1. (2) The sum of all probabilities of the distribution sum up to 1.
In the discrete probability distribution what is the sum of all probabilities?
The sum should equal to 1.
What is the sum of the probabilities of all outcomes in a sample space?
1
What is the sum of the probabilities of all the 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 is the sum of the probabilities of all of the outcomes in a sample space?
one (1)
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.
What is the sum of the probabilities of each outcome multiplied by the outcome value?
expected value
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.
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.
