8)AnB=everything outside An B.An B did not occur,soanB did occur. 1)Yes 2)No 3)No 4)Yes 5)No 6)Yes 7)No 8)Yes Question:What is the event ?=0 Chanllenge:Can you express B using only a sign? Answer:A0B=(B). Limitations of Venn diagrams Venn diagrams are generally useful for up to 3 events,although they are not used to provide formal proofs.For more than 3 events,the diagram might not be able to represent all possible overlaps of events.(This was probably the case for our transport Venn diagram.) Example: (a)AUBUC (b)AnBnc 61256 / 25 did occur. 1)Yes 2) No 3)No 4) Yes 5) No 6) Yes 7) No 8) Yes. Chanllenge: Can you express A∩ B using only a ∪ sign? Answer: A∩ B = (A∪ B). Venn diagrams are generally useful for up to 3 events, although they are not used to provide formal proofs.
