A town recently dismissed 5 employees in order to meet their new budget reductions. The town had 4 employees over 50 years of age and 16 under 50. If the dismissed employees were selected at random, what is the probability that no more than 1 employee was over 50

0.7513 = 75.13% probability that no more than 1 employee was over 50

Step-by-step explanation:

The employees 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 following formula:

In which:

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.

Combinations formula:

is the number of different combinations of x objects from a set of n elements, given by the following formula.

In this question:

4 + 16 = 20 employees, which means that

4 over 50, which means that

5 were dismissed, which means that

What is the probability that no more than 1 employee was over 50?

Probability of at most one over 50, which is:

In which

Then

0.7513 = 75.13% probability that no more than 1 employee was over 50

it would to have a graph or something ! but i had this question so its false
