This is valid. However, for the reasons I am interested in the problem (which I am not going to describe now) I don’t get any to consider those probabilities. Pretend that I am stubborn, and refuse to consider anything other than p and q, but still would like advice on how to combine them.
If I’m the person who came up with probabilities p and q in the first place, surely I know how I came up with those probabilities.
