This then leads to further rules
Every pair of events are independent of each other
The probability of all of a subset of events happening in the multiplication
The probability that a variable takes a certain value
The probability $A=x$ and $B=y$ is the probability $A=x$ multiplied by the probability $B=y$
The expected value is x times the probability of x for all x
This can also be shown as the area under the curve
The expected value of A and B is the expected value of A plus the expected value of B
This doesn’t apply for multiplication, only if they are independent
