Imagine
A 60 year old person has 1/20 risk to die during a certain year
The amount of sigarets smoked a day increases the risk with +1/20
Each cup of coffee lowers the risk with -0.2/20
If a certain 60 year old smokes 2 sigarets each day and drinks 3 cups of coffee what is his risk to die
==> Is this
1/20 + (2*1)/20 - (3*-0.2)/20 = 2,4/20 ?
