Here is a handy table showing all 3 methods (the interval is 1 to 2): Example: to include 1, and not include 2: And it is fair to say all prices are more than $0.00. Copy and paste. P(EIF)=P(E (upside down U) F)/ P (F) When using tree diagrams, just find the path that gives you the answer and multiply all #s along that path, paying EXTREMELY CLOSE detail to the numbers (it can be tough) and add them For example, dF/dx tells us how much the function F changes for a change in x. So fair enough, those are just two set definitions. In which case, ∩ is the intersection. Not sure if both these symbols relate in any way.
