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 ...
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 ...
This can easily be computed using the law of total probability, conditioning on each possible genotype j at the locus and summing over all possible genotypes. For a particular genotype j, we com- pute P(E|j) the same way as in the numerator. This is the probability of the necessary ...
VaR is a statistical technique used to measure the amount of potential loss that could happen in an investment portfolio over a specified period of time. Value at Risk gives the probability of losing more than a given amount in a given portfolio. ...
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...
A. Use the information in the table below to find the average severity per claim. B.Use the information in the table above to estimate a probability distribution for the loss severity per claim. Ran Refer to the gasoline sales time series data in the following table. Using a weight 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...
