Since purchasing new gear will reduce cash flow by $5,000, the corporation should keep its old equipment, and the calculation can be defined as follows:
<h3 /><h3>Calculating the Total decrease in net income:</h3>The following are the costs if the company keeps the old equipment:
$30,000 x 3 years = $90,000 So, the total cost is $90,000.
The following are the costs if the company purchases new equipment:
Calculating the equipment cost that is
$75,000 - $10,000 = $65,000.
$10,000 x 3 years = $30,000. So, the total cost is $95,000.

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%.
