3. Indifference curves and preferences Edison likes both chocolate and ice cream. Assume that the more is better" principle applies to Edison; that is, he would always prefer to consume more of either good, holding the consumption of the other good constant. The points on Figure 1 represent combinations of ice cream and chocolate that Edison might choose to consume. Figure 2 shows the same points as Figure 1, but it also shows some of Edison's indifference curves: 11, 12,...

Among 450 randomly selected drivers in the 20-24 age bracket, 9 were in a car crash in the last year. If a driver in that age bracket is randomly selected, what is the approximate probability that he or she will be in a car crash during the next year? Is it unlikely for a driver in that age bracket to be involved in a car crash during a year? Is the resulting value high enough to be of concern to...
