hello :)
i have a silly question and i keep confusing myself, hope someone can help me.
my friend has two diseases and I want to calculate a number to represent the chance of success (i.e. him surviving both diseases for more than 5 years)
disease A: chance of survival for more than 5 years, using certain treatment = 29%
disease B: chance of survival for more than 5 years, using the same treatment as A = 21%
both diseases are not related and don't affect each other but both contribute to failure of the treatment i.e. dying and not passing 5 years...
now, should I simply get the average of the two numbers (25%) or its supposed to be calculated in other way?
i keep confusing myself by thinking, the chance of passing 2 life threatening diseases at the same time should be lower than that!
