Using the hypergeometric distribution, it is found that the probability is 0.845 = 84.5%.
--------------------
- The patients are chosen from the sample without replacement, which means that the hypergeometric distribution is used to solve this question.
Hypergeometric distribution:
The probability of x successes is given by:

The parameters are:
- x is the number of successes.
- N is the size of the population.
- n is the size of the sample.
- k is the total number of desired outcomes.
Combination formula:
is the number of different combinations of x objects from a set of n elements, given as:

--------------------
- 56074 patients, thus

- Sample of 40, thus,

- 235 left against medical advice, thus,
.
The probability that none left against medical advice is P(X = 0), so:


The probability is 0.845 = 84.5%.
