Hi guys - same again, my exam is tomorrow and I have a quick question.

With calculation the range of estimated duration +- standard deviation, if we get a question like this on exam how do we know whether to use the triangular formula or the PERT formula.

Thanks to anyone

Hi Ruby.

Usually, the exam question will state which method to use.

Once again, I wish you the very best in your exam.
