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.
