Interested in statistics, machine learning, applied algebraic topology. Pure math is also interesting too, particularly topology and geometry.

Thanks that makes sense. Does one of you want to write it in an answer so that I can accept it?

Also, does player 2 know that player 1 knows their probability distribution?

comment Calculating probabilities from incomplete data
That is what I think-although it would be worthwhile to check for relationships, I guess you have your numerical data to do that.

The second table doesn't matter if the first table corresponds to the same observations.

Oh, it isn't in your table, but I am giving an example of something that could happen.

Are you using your first data table, or your second? It makes a big difference. E.g. a doctor who touches a table >2 times will touch the bed, whereas one who only touches the table once will not touch the bed.

If you have no additional information about the new doctor we are predicting for-(how many things he will touch, which rooms he will be in), then the probability should just be the proportion of the 100 who touched the table, and the expectation should be the mean. When I answered earlier for some reason I though you had additional information.

Ah I thought that there could be more than one surface in each room, and that is how I framed my answer. Let me think about it a bit :p

The second part is conditional probability

comment Calculating probabilities from incomplete data
Are you looking for the conditional expectation of how many tables they touched, given the total surfaces touched? Or are you not making any inferences from how much surfaces were touched?
