200 Patients: 40C 100C 60D
A)what is the probability that 5 cardiac and 10 cancer patients
are given free medical treatment: 15 PATIENTS
P = (40C5)(100C10)/(200C15)
B)what is the probability that 2 cardiac 5 cancer and 4 diabetics patients
are given free medical treatment: 11 PATIENTS
P = (40C2)(100C2)(60C4)/(200C11)

~~~~~~~~~~~~~
This problem is posed and is formulated INCORRECTLY.
I explained it at least 5 times before, when the problem was posted earlier to this forum months ago.
In this form, as it is worded, printed, posted and presented, it is incorrect and MAKES no SENSE.
The "solution" by @ewatrrr is this sense is empty and also nonsensical.
It would make sense ONLY IF the number of served patients is given EXPLICITLY in the condition,
but in this problem IT IS NOT DEFINED, making the problem nonsensical.
When the visitors re-post it again and again, after getting my explanations several times,
it produces really poor impression.
You, the visitor, must learn THESE TWO THINGS from my post :
(a) The person who composed this text/post/problem, is INCOMPETENT in this class of problems.
(b) The source from which you recovered this "problem", DOES NOT DESERVE any trust.
