Dear Rainer,
If X1 is random on 1:20 with probabilities proportional to
dnorm(,10,2), and X2 is random on 10:30 with probs proportional to
dnorm(,15,1), and the object is to find out the probability
distribution of X1 + X2, then a very quick way is with package distr:
library(distr)
X1 <- Discret

Hi
I have two processes which take with a certain probability (p1 and p2) x
number of years to complete (age1 and age2). As soon as thge first
process is completed, the second one begins. I want to calculate the
time it takes for the both processes to be completed.
I have the following script
