If X is a discrete variable then

E(X) is the sum of x*Prob(X = x) where the summation is over all possible values of x.

What does uniform probability mean in math?

Uniform probability can refer to a discrete probability distribution for which each outcome has the same probability. For a continuous distribution, it requires that the probability of the outcome is directly proportional to the range of values in the desired outcome (compared to the total range).

The expected value is what kind of aspect of how probability distribution is characterized?

Expected value is the outcome of confidence of how probability distribution is characterized. If the expected value is greater than the confidence interval then the results are significant.


What is the expected outcome of a hypothesis?

what is expected is to see if the outcome of the factor increases or decreses


How do you construct a probability distribution?

First decide whether the event space is discrete or continuous.For a discrete event space, for each outcome in the space assign a probability: a number in the interval [0, 1] such that the sum of probabilities for all outcomes is 1. The mapping from the event space to the probabilities is the probability distribution function.The procedure for a continuous event space is analogous: the sum is replaced by the integral.
