Probability Distribution

An array that lists all possible outcomes of an event and their corresponding probabilities of occurrence.

Mean/Standard Deviation Model Advantage

A primary benefit of this model is its ability to eliminate subjective bias in risk assessment.

Joint Probabilities

Probability of Occurrence

The chance or likelihood associated with a particular outcome.

Mean/Standard Deviation Model Limitation

This model isn't effective when cash flows are perfectly correlated because there's no uncertainty or variation.

Study Notes

Probability Distributions and Risk Assessment

  • A probability distribution displays all possible outcomes and their probabilities.
  • A key example is a probability distribution.
  • A primary benefit of the mean/standard deviation model is that it isolates risk assessments from an analyst's personal risk preferences.
  • This model helps communicate risk assessments objectively.
  • Statistical sampling techniques can create objective risk estimates.

Joint Probabilities

  • Joint probabilities describe the probability of two or more related events occurring together.

Probability of Occurrence

  • Probability represents the chance of an outcome occurring.

Mean/Standard Deviation Model Limitations

  • The mean/standard deviation model is not limited by the number or timing of cash flows.
  • It isn't affected by perfect correlation of cash flows.
  • The model works best with symmetrical probability distributions.

Subjective Probability Distributions

  • Subjective probability distributions reflect an analyst's assessment of risk in cash flow, it's not objective.

Risk Definition

  • Contemporary risk analysis defines risk as a measurable likelihood of deviation from the most probable outcome.

Probability Ranges

  • Probabilities are between zero and one; they cannot be negative or infinite.

Expected Value Calculation

  • The expected value of a probability distribution represents the weighted average of possible cash flows. Each cash flow is weighted by the probability of its occurrence.

Standard Deviation Model Applicability

  • The standard deviation model works best when the probability distribution is approximately symmetrical to the mean.
