We study identities and their manipulations.
In particular, w study using brute force, as well as identities with fractions.

Two events are called to be independent events if the occurrence or non-occurrence of one event does not affect the probability of the other event.
If A and B are independent events, the probability of both events A and B occurring is the product of their individual probabilities:
P(A and B) = P(A) * P(B)
With this, we can simplify tree diagrams when dealing with problems with multiple same items by simply marking their probabilities.
When two (or more) events are dependent to each other, we cannot use the product rule, but we can still use the tree diagrams to help us finding probabilities.
