What Is Probability? What Are Its Characteristics

Question

Examlex · Accepted Answer

The Answer is Probability is the likelihood that an outcome occurs.
Suppose we label the n outcomes in a sample space as O1,O2,…,On,where Oi represents the ith outcome in the sample space.Let P(Oi)be the probability associated with the outcome Oi.Then:
•The probability associated with any outcome must be between 0 and 1,or

0 \leq P\left(O_{i}\right) \leq 1

for each outcome Oi
•The sum of the probabilities over all possible outcomes must be 1.0,or
P(O1)+ P(O2)+ ...+ P(On)= 1
