TABLE 19-1 The following payoff table shows profits associated with a set of 3 alternatives under 2 possible states of nature -Blossom's Flowers purchases roses for sale for Valentine's Day.The roses are purchased for $10 a dozen and are sold for $20 a dozen.Any roses not sold on Valentine's Day can be sold for $5 per dozen.The owner will purchase 1 of 3 amounts of roses for Valentine's Day: 100,200,or 400 dozen roses.If the probability of selling 100 dozen roses is 0.2 and 200 dozen roses is 0.5,then the probability of selling 400 dozen roses is

TABLE 19-6 A student wanted to find out the optimal strategy to study for a Business Statistics exam.He constructed the following payoff table based on the mean amount of time he needed to study every week for the course and the degree of difficulty of the exam.From the information that he gathered from students who had taken the course,he concluded that there was a 40% probability that the exam would be easy. -True or False: Referring to Table 19-6,the optimal strategy using the return-to-risk ratio criterion is to study 8 hours per week on average for the exam.

At Eastern University,60% of the students are from suburban areas,30% are from rural areas,and 10% are from urban areas.Of the students from the suburban areas,60% are nonbusiness majors.Of the students from the rural areas,70% are nonbusiness majors.Of the students from the urban areas,90% are nonbusiness majors.If a randomly selected student is not a business major,the probability that the student is from the urban area is
