  • 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 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...

When we think about how much this concept pops up within our daily lives, we might be shocked to find the results.
