Let's suppose we are estimating a task (not by the planning poker). We have discovered that there are a few possible problems (risks): risk1
Risk 1 - with the probability p1, ..., riskNrisk N - with the probability pN.
Each problem increases the amount of work. But only some of these problems willmay happen.
There are also some other problems which can arise (additional risks) only if some of the abovementionedabove-mentioned risks do happen.
What is the way to calculate an estimationestimate for this kind of task?
