“How can we attribute what is responsible for climate change?”

One of the biggest debates going on about climate change is what is causing it. Many political pundits will claim that everything can be explained entirely through natural factors such as the Earth’s tilt or volcanoes. However, to prove causation, mathematical analysis will need to be done to isolate each component and observe its effects. Using this Climate Change Attribution, we can see that these effects do not contribute greatly to global warming and that carbon emissions is the primary driver behind climate change.

“How can we predict the value of an item at the end of its lifetime?”

Due to the second law of thermodynamics, materials are bound to degrade over time, lowering both its function and value. Since an item might become less worthy in the future, then it would be very useful to know how it will change. Through analytical modeling and past experience, we can calculate something the Residual Value, or final worth of a product. Many leasing companies will calculate monthly payments based on this final value.

“How can we measure the probability of drawing something without replacement?”

Sometimes, we would like to know the probability of choosing certain types of cards and that we either choose the right or wrong card. The problem with this is that the probability will change with each card drawn. As a result, this will take on a special Hypergeometric Distribution.

The probability of choosing the desired card can be found with the equation

With N being the total population, n being the number of draws, K being the number of successful members of the population, and k being the amount of the successful members desired.
