Statistics is based upon based upon common sense and logic, in a complex data. Probability is just one of the many topics in statistical mathematics. It is used in our daily life, all over the world. Even games, require taking a chance and using probability to determine the predicted outcomes.

Probability is the measure of how often a particular event will happen if something is done repeatedly, (596 Webster’s Dictionary). You cannot determine any events that will happen in the future, because there is always a chance that something odd will happen, (Linn 39-40).

Probability originally started for the purpose and attempt to analyze games of chance. Probability is also used in determining the outcomes of an experiment. Sample space is the collection of all results. Probability is a way to assign every event a value between zero and one.

What is the probability of rolling a pair of dice, or a deck of cards, or a jar of marbles? What is the probability of conceiving a boy or a girl? Many more are determined by the usage of the probability method.

Probability is used to represent the likelihood that odds of winning a random drawing chance of rolling a seven when rolling two dice. When rolling a six-sided die there are six possible events that correspond to the six face of the die that contains either one, two, three, four, five, and six dots. Rolling a die and turning up an even number of dots would be one example, (2, 4, and 6).

Probabilities are formally written as decimals in the range of 0-1. Meaning the event occurred. Meaning a certain event must occur. When rolling a die, getting a seven, eight, or nine or more dots is an impossible event. Two dots or fewer are a certain event.

Probabilities can also be written informally in percentage for example 50-50-%. There is no negative probability chance. The probability of getting a face that has two dots on a die is 1/6(1....

RANDOM VARIABLES AND PROBABILITY DISTRIBUTION
Random variables is a quantity resulting from an experiment that, by chance, can assume different values. Examples of random variables are the number of defective light bulbs produced during the week and the heights of the students is a class. Two types of random variables are discrete random variables and continuous random variable.

Random Process
In a random process we know that what outcomes or
events could happen; but we do not know which
particular outcome or event will happen. For
example tossing of coin, rolling of dice, roulette
wheel, changes in valuation in shares, demand of
particular product etc.

...PROBABILITY DISTRIBUTION
In the world of statistics, we are introduced to the concept of probability. On page 146 of our text, it defines probability as "a value between zero and one, inclusive, describing the relative possibility (chance or likelihood) an event will occur" (Lind, 2012). When we think about how much this concept pops up within our daily lives, we might be shocked to find the results. Oftentimes, we do not think in these terms, but...

...variable X is a weighted average of the possible values that the random variable can take. Unlike the sample mean of a group of observations, which gives each observation equal weight, the mean of a random variable weights each outcome xi according to its probability, pi. The mean also of a random variable provides the long-run average of the variable, or the expected average outcome over many observations.The common symbol for the mean (also known as the expected value of X)...
