I think the question needs to give a bit more detail.

B's biodata

B is a fictitious character, as are the rest.

Now that I have 2 combinatoricists confirm, I am sure I am correct.

Can I have a fictitious biodata, then?

I have not fleshed any of them out to avoid someone thinking that some letter corresponded to him/her. When I first used that format I thought it would be an amusing way to get some interest in the problems.

I will drop that format. I have had people who believe that the letters stand for them. I have joking said the characters are based on real live people and was misunderstood.

This is why I thought you were becoming too serious. You are getting worried over trivial things and think that we are so sensitive that we will get upset over such small things.

Me, Elaina and bobbym are interpreting the tests as indistinguishable with the days being distinguishable and the ways to arrange that is 70. Then, the possibilities where there is only one test is 5. Therefore, we got 65/70, which is different from Stefy's answer?

It's not different. Look at the two more carefully.

Do you guys really not realize the I just cancelled the factor 5 in 65/70 to get 13/14?

There should be a Psi in there. It is the symbol for psychology.
