Equilibrium price. Equilibrium allocation: x=xi(p,p·w2), Note: A p* for any >0 is also an equilibrium price. Offer curve: (p)(p, p. w;). The equilibrium is the intersection point of the offer curves. Excess demand function:
In the special case when E's are conditionally independent(though they all depend on the alternative, Ak), P(, E2..)= P(A... -)P() ()P) This is easy to do and can be done recursively
1、解: (1) P{只订购 A 的}=P{A(B∪C)}=P(A)-{P(AB)+P(AC)-P(ABC)}=0.45-0.1.-0.08+0.03=0.30. (2) P{只订购 A 及 B 的}=P{AB}-C}=P(AB)-P(ABC)=0.10-0.03=0.07 (3) P{只订购 A 的}=0.30
16.322 Stochastic Estimation and Control Professor Vander Velde 1. P(ABCD.=P(A)P(B A)P(C|AB)P(D 1 ABC) Derive this by letting A=CD. Then P(BCD)= P(CD)P(B ICD)= P(C)P(DIC)P(DICD) 2. If A,, A2r.. is a set of mutually exclusive and collectively exhaustive events, then
