• What Is a Random Variable?
WHAT IS A RANDOM VARIABLE? A random variable assigns a number to each outcome of a random circumstance, or, equivalently, a random variable assigns a number to each unit in a population. It is easier to create rules for broad classes of situations and then identify how a specific example fits into a class than it is to create rules for each specific example. We can employ this strategy quite effectively for working with a wide variety of situations Involving probability and random outcomes....

• Risk-Return Relationship - 889 Words
﻿CHAPTER 22 estimating risk and return on assets 1. WHAT IS RISK? Risk is the variability of an asset’s future returns. When only one return is possible, there is no risk. When more than one return is possible, the asset is risky. The greater the variability, the greater the risk. 2. RISK – RETURN RELATIONSHIP Investment risk is related to the probability of actually earning less than the expected return – the greater the chance of low or negative returns, the riskier the...

• Probability Distribution Essay - 256 Words
Probability Distribution Essay Example Suppose you flip a coin two times. This simple statistical experiment can have four possible outcomes: HH, HT, TH, and TT. Now, let the random variable X represent the number of Heads that result from this experiment. The random variable X can only take on the values 0, 1, or 2, so it is a discrete random variable Binomial Probability Function: it is a discrete distribution. The distribution is done when the results are not ranged along a wide range, but...

• Binomial, Bernoulli and Poisson Distributions
Binomial, Bernoulli and Poisson Distributions The Binomial, Bernoulli and Poisson distributions are discrete probability distributions in which the values that might be observed are restricted to being within a pre-defined list of possible values. This list has either a finite number of members, or at most is countable. * Binomial distribution In many cases, it is appropriate to summarize a group of independent observations by the number of observations in the group that represent one...

However, when the demand rate is not constant and not deterministic, the inventory model is called probabilistic and is best described by a probability distribution.

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 imagine what the probability of us getting...
