a doctor recommends one of two treatments for a serious illness. treatment a has a 70% chance of full recovery but a 30% chance of death. treatment b has a 99% chance of survival with permanent disability and a 1% chance of full recovery. which treatment is generally considered safer?
treatment b
treatment a
they are equally safe.
it depends on the cost of treatment.

Explanation:

Step1: Analyze death - chance of Treatment A

Treatment A has a 30% chance of death.

Step2: Analyze death - chance of Treatment B

Treatment B has a 1% chance of full - recovery and 99% chance of survival with permanent disability, so the chance of death is 0%.

Step3: Compare death - chances

Since 0% (Treatment B's death - chance) < 30% (Treatment A's death - chance), Treatment B is safer.

Answer:

A. Treatment B
