1.1: Events and Their Outcomes

In probability theory, an event is a set of outcomes that share a particular property or characteristic. For example, when rolling a six-sided die, the event "rolling an even number" includes the outcomes 2, 4, and 6. Events can be represented using set notation, where the sample space (Ω) represents all possible outcomes of an experiment.

The sample space for rolling a six-sided die can be represented as:

Ω = {1, 2, 3, 4, 5, 6}

The event "rolling an even number" can be represented as:

E = {2, 4, 6}

Summary

  • An event is a set of outcomes that share a particular property or characteristic.
  • Events can be represented using set notation.
  • The sample space represents all possible outcomes of an experiment.

1.2: Sample Spaces

A sample space is a set of all possible outcomes of an experiment. The sample space can be finite or infinite, depending on the nature of the experiment. For example, the sample space for rolling a six-sided die is finite, while the sample space for measuring the weight of an object is infinite.

To determine the sample space for an experiment, we need to identify all possible outcomes. For example, the sample space for flipping a coin twice can be represented as:

Ω = {HH, HT, TH, TT}

where H represents heads and T represents tails.

Summary

  • A sample space is a set of all possible outcomes of an experiment.
  • The sample space can be finite or infinite.
  • To determine the sample space, we need to identify all possible outcomes.

1.3: Probability Measures

A probability measure is a function that assigns a probability to each event in the sample space. The probability of an event is a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

There are three methods for calculating the probability of an event:

  1. Classical Probability: This method is based on the assumption that all outcomes are equally likely. The probability of an event is calculated as the ratio of the number of favorable outcomes to the total number of outcomes.

For example, the probability of rolling a 4 on a six-sided die is:

P(4) = 1/6

  1. Empirical Probability: This method is based on the observed frequency of an event. The probability of an event is calculated as the ratio of the number of times the event occurred to the total number of trials.

For example, if we roll a six-sided die 100 times and observe that the number 4 appears 15 times, the empirical probability of rolling a 4 is:

P(4) = 15/100

  1. Theoretical Probability: This method is based on a mathematical model of the experiment. The probability of an event is calculated using a probability distribution or a probability density function.

For example, the probability of rolling a number less than or equal to 4 on a six-sided die is:

P(X ≤ 4) = 4/6

Summary

  • A probability measure is a function that assigns a probability to each event in the sample space.
  • The probability of an event is a number between 0 and 1.
  • There are three methods for calculating the probability of an event: classical, empirical, and theoretical.

1.4: Probability Rules

There are three fundamental probability rules:

  1. Addition Rule: The probability of the union of two events is the sum of their probabilities minus the probability of their intersection.

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

  1. Multiplication Rule: The probability of the intersection of two events is the product of their probabilities.

P(A ∩ B) = P(A) * P(B|A)

  1. Conditional Probability: The probability of an event given another event is the ratio of the probability of their intersection to the probability of the second event.

P(A|B) = P(A ∩ B) / P(B)

Summary

  • There are three fundamental probability rules: the addition rule, the multiplication rule, and conditional probability.
  • The addition rule is used to calculate the probability of the union of two events.
  • The multiplication rule is used to calculate the probability of the intersection of two events.
  • Conditional probability is used to calculate the probability of an event given another event.

2.1: Applications in Statistics

Probability theory has numerous applications in statistics, including hypothesis testing, confidence intervals, and statistical inference.

Hypothesis testing is a statistical method used to test a hypothesis about a population parameter. The hypothesis is tested by comparing the sample statistic to a critical value or a p-value. The critical value or p-value is determined based on the probability distribution of the sample statistic.

Confidence intervals are used to estimate a population parameter with a specified level of confidence. The confidence interval is calculated based on the sample statistic and the probability distribution of the sample statistic.

Statistical inference is the process of drawing conclusions about a population based on a sample. Statistical inference is based on probability theory, which provides a framework for modeling and analyzing data.

Option pricing is the process of determining the price of an option, which is a contract that gives the holder the right, but not the obligation, to buy or sell an asset at a specified price. Option pricing is based on probability theory, which provides a framework for modeling the uncertainty of the asset's price.

Risk management is the process of identifying, assessing, and mitigating risks in a financial portfolio. Risk management is based on probability theory, which provides a framework for modeling and analyzing the probability of different outcomes.
