Quick Recall Flashcards

What does A ∩ B mean?
The intersection - outcomes where BOTH event A AND event B occur. On the diagram it is the overlapping region between the two circles.
What does A ∪ B mean?
The union - outcomes where AT LEAST ONE of event A or event B occurs. Includes only A, only B, and A ∩ B. The ∪ symbol looks like a U for Union.
