probability theory, a branch of mathematics concerned with the analysis of random phenomena. The outcome of a random event cannot be determined before it occurs, but it may be any one of several possible outcomes. The actual outcome is considered to be determined by chance.
Probability, or probability theory in application to mathematics, is the measurement of the possibility of a particular outcome.
As a mathematical foundation for statistics, probability theory is essential to many human activities that involve quantitative analysis of data. Methods of probability theory also apply to descriptions of complex systems given only partial knowledge of their state, as in statistical mechanics or sequential estimation.
Probability theory is all “Slow” System II is slow, but it's also hard; it demands energy, will-power and — certain mind states aside — it is a limited resource. Because Probability Theory is non-intuitive, it is perpetually doomed to languish in System II thought paradigms.
Statistics does tend to be harder than calculus, especially at the advanced levels. If you take a beginning statistics course, there will be very simple concepts that are rather easy to work out and solve.
Statistics has gotten a reputation for being a very hard class, especially when taken in college, because it combines math concepts in order to form an analysis of a data set that can be used to understand an association in the data (whoo that was a mouthful).
The probability theory is very much helpful for making prediction. Estimates and predictions form an important part of research investigation. With the help of statistical methods, we make estimates for the further analysis. Thus, statistical methods are largely dependent on the theory of probability.
Probability plays a vital role in the day to day life. In the weather forecast, sports and gaming strategies, buying or selling insurance, online shopping, and online games, determining blood groups, and analyzing political strategies.
Probability provides information about the likelihood that something will happen. Meteorologists, for instance, use weather patterns to predict the probability of rain. In epidemiology, probability theory is used to understand the relationship between exposures and the risk of health effects.
In summary, probability is difficult to teach, because we should not only present different probabilistic concepts and show their applications, but we have to go deeper into wider questions, consisting of how to interpret the meaning of probability, how to help students develop correct intuitions in this field and deal ...

Each coin can land on heads or tails. And each out color is equally likely at 1/2.
The statistical education literature appears to be consistent and unequivocal about this issue: probability is not statistics, statistics is far more than probability, and statistics (at least at the K-12 and college levels) should be introduced as thinking with data rather than as an application of probability.
