A "p" is used for probability of success. A "q" is used for probability of failure.

The symbol for probability of success in a binomial trial is the letter p. It is the symbol used for probability in all statistical testing.

Inferential statistics are used in situations where it can be assumed that random behaviour(s), subject to the mathematical laws of probability, must be taken into account.

It is used when repeated trials are carried out , in which there are only two outcomes (success and failure) and the probability of success is a constant and is independent of the outcomes in other trials.

Probability is used to answer questions in the category of Statistics. Probability is a basic statistic that gives numeric value to the questions; Will a specific event occur? or How certain are you that it will occur. Probability of rolling a 3 on a 6-sided die is 1/6.

Since this is regarding statistics I assume you mean lower case sigma (σ) which, in statistics, is the symbol used for standard deviation, and σ2 is known as the variance.

Probability is related to statistics in a direct manner. When one is doing a research for statistics, probability has to be used especially in sampling a small region.

Statistics is based on probability theory so each and every development in statistics used probability theory.

All the time. Statistic is based on the application of probability theory!

Usually mu is the symbol for the mean of a probability distribution. It is sometimes used as the average of a dataset (also called the mean of the dataset), although I prefer to use "x bar".

Yes; the p value used in hypothesis testing is probability. See the related link.

Statistics is used in many places especially when you are the head of a business and you need to calculate probability and things like that.
