Set Theory

You've often heard about the probabilities — for instance, the likelihood of rain or sunny weather. The probability of 95% sunny weather ensures that a picnic is the best idea; meanwhile, the same chance of rain forces you to stay home.

In this course, we will work with the probabilities, but let's first figure out what a set theory is.

Examples of sets:

• Ingredients for the dinner: {Chicken, Carrot, Rice, Ollive oil, Cheese}
