plain orbit
I am having a little trouble trying to understand how we go from step 4 to 5 (green arrow). I understand that when we subtract A and B, we have to add the intersection of the two so we dont double count.
The intersection can be written as A intersection B or A time B.
Then that gives us the space outside the two events... Which is the complement of both A and B...
So that entire space between 1 and A&B is the complement intercept?

Step 4 to step 5 is just simple factoring. Try going from step 5 to step 4 by expanding

$1-P(A)-P(B)+P(A)P(B) = 1-P(A)-P(B)-P(B)(-P(A))$

It’s the PB portion that is giving me a brain fart.
I went through it slowly with a ven diagram and in understand now. Thanks for your help guys
