Q1. James and Jamie are two salespersons in the same team. Every month, the amount ofsales that James secures is uniformly distributed between $9,500 and $10,500; and everymonth, the amount of sales that Jamie (independently) secures is uniformly distributedbetween $9,000 and $11,000. What is the probability that in the next month, James willsecure more sales than Jamie? Explain your answer carefully Q2. The lifetimes of a specific brand of alkaline batteries (measured in hours) isexponentially distributed with mean lifetime of 20 hours. Alex just buys two batteriesof this brand and labels them Battery A and Battery B. Then, Alex uses them to powerhis computer mouse, which requires two batteries to operate. The mouse is extremelysensitive to its power supply, in the sense that if any of the two batteries run out, it canno longer operate. What is the probability that the operating time of Alex’s computermouse with Batteries A and B is less than 20 hours?

A buyer and a seller are bargaining over the sale of an object. The buyer knows that the seller values the object $0 with a probability of 0.25 and he values it $4 with a probability of 0.75. The seller knows that the buyer values the object either $1 or $5, each with a probability of 1/2. The table below shows what happens in each contingency Seller's value is $0 Seller's value is $4 Buyer's value is $1 Trade price is $1 NO TRADE Buyer's value is $5 Trade price is $p Trade price is $4 Find the interval for p such that The buyer with a valuation of $5 is not better-off reporting $1 The seller with a valuation of $0 is not better-off reporting $4.
