expected average outcome over many observations.The common symbol for the mean (also known as the expected value of X) is ‚ formally defined by Variance - The variance of a discrete random variable X measures the spread‚ or variability‚ of the distribution‚ and is defined by The standard deviation is the square root of the variance. Expectation - The expected value (or mean) of X‚ where X is a discrete random variable‚ is a weighted average of the possible values that X can take‚ each value

Probability distribution Definition with example: The total set of all the probabilities of a random variable to attain all the possible values. Let me give an example. We toss a coin 3 times and try to find what the probability of obtaining head is? Here the event of getting head is known as the random variable. Now what are the possible values of the random variable‚ i.e. what is the possible number of times that head might occur? It is 0 (head never occurs)‚ 1 (head occurs once out of 2 tosses)

Distribution channel plays an important part in the supply chain. Distribution channel‚ as defined by Coughlan et al. (2006)‚ is a set of independent organizations involved in the process of making a product or service available for consumption. It serves as the connecting link between the producer and consumer by adding value to products or services (Kim and Frazier‚ 1996) and multiplies selling opportunities through network of intermediaries. These independent organizations are usually made of

Equal growth of income can be achieved by re-evaluation of monetary distribution within corporations to increase raises for workers and eliminate executive bonuses. The distribution of wealth within a corporation is about as fair as 300 against one in a game of dodge ball.
