The tree diagram for the toss of a coin given below helps in understanding the possible outcomes when a coin is tossed. Each branch of the tree is associated with the respective probability (just like how 0.5 is written on each brack in the figure below). Remember that the sum of ...

The AUC of a classification model is defined as the probability that the model will rank a random positive example above a random negative example. Using the confusion matrix, we can define other quantities as follows: The True Positive Rate (TPR) or sensitivity is the the ratio of data poin...
Between the three links and reference pages above we review a number of real world cases, applying Value at Risk (VaR) approaches to the following risk problems: Risk management within the petrochemical industry (probability of shortfall applied to crude oil volatility at an oil refinery), The v...
The temperature is recorded at 60 airports in a region. The average temperature is 67 degrees Fahrenheit with a standard deviation of 5 degrees. What is thez-score for a temperature of 68 degrees? A group of friends compares what they received while trick or treating. They find that the av...
IQR Calculation using Excel: In Excel, there is no direct way to calculate the Interquartile range. The most common approach is to calculate the third and first quartiles using the quartile function in Excel and then find out the difference (Q3-Q1) between them. ...

First, they calculated the probability of the hands by combinatorial formulae. Then, they verified the result with a spreadsheet model developed in the lesson. The students were given a questionnaire to find out if they found the lesson interesting and contributing to their mathematical and ...
Next, risk-reward gives you no indication of probability. What if you took your $500 and played the lottery? Risking $500 to gain millions is a much better investment than investing in the stock market from a risk-reward perspective, but a much worse choice in terms of probability. ...
