Two different chemotherapy regimens can be used to treat breast cancer. Treatment with doxorubicin is known to show a remission rate 40% of the time. This treatment costs $1,000. The other treatment, docetaxel, shows a remission rate 25% of the time and costs $850. The two treatment plans are: Plan A: Treat with doxorubicin. If not effective, treat with docetaxel. Plan B: Treat with docetaxel. If not effective, treat with doxorubicin. Based on the data provided, what is the probability that a patient treated under plan A will show remission?
