5. Let E and F be two events in an experiment. (a) Explain, using a Venn diagram, why (b) Explain why this implies that (c) Justify why E = (EnF)u(EnF") and P(E) = P(En F) + P(En Fª) P(F|E) P(E|F)P(F) P(E|F)P(F) + P(E|Fc)P(Fe) are equal by showing a computation that starts at P(FE) and ends at the term above, with each step a clear application of a formula or axiom we learned in class.

5. Let E and F be two events in an experiment.
(a) Explain, using a Venn diagram, why
(b) Explain why this implies that
(c) Justify why
E = (EnF)U(EnF")
and
P(E)=P(En F) + P(En Fe)
P(FE)
P(E|F)P(F)
P(E|F)P(F) + P(E|Fe) P(Fe)
are equal by showing a computation that starts at P(FE) and ends at the term
above, with each step a clear application of a formula or axiom we learned in
