Probability

Probability is the study of random events. Computers are particularly helpful here as they can be used to carry out a number of experiments to confirm and/or explore theoretic results.

In practice studying probability will often involve:

• calculating expected chances of an event occurring;

• calculating the conditional chances of an event occurring given another event occurring.

Here we will see how to instruct a computer to sample such events.

Important

In this chapter we will cover:

• Generating random numbers.

• Randomly sample from a given collection of items.

• Write python functions to be able to repeat experiments.
