Suppose two drugs are routinely used for treatment of a particular kidney disorder. Drug 1 is known to cure the disease 85% of the time and costs $90. Drug 2 is known to cure the disease 70% of the time and costs $65. The two drugs work independent of each other (that is, administration of one has no effect on the efficacy of the other). The two treatment plans are as follows:Plan A: Treatment with Drug 1—if not effective, treatment with Drug 2.Plan B: Treatment with Drug 2—if not effective, treatment with Drug 1.Which statement is most correct in this situation?\Based on the overall probability of a cure, plan A should be selected over plan B.Based on the overall probability of a cure, plan B should be selected over plan A.Based on the overall cost of treatment, plan A should be selected over plan B.Based on the overall cost of treatment, plan B should be selected over plan A.Based on the probability of a cure and the cost of treatment, both plans are equivalent, so either can be selected.
