An election ballot asks voters to select three city commissioners from a group of six candidates. If your aunt and father are running, what is the probability that either your aunt or your father will become a city commissioner

0.8 = 80% probability that either your aunt or your father will become a city commissioner.

Step-by-step explanation:

The candidates 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:

6 candidates, which means that

2 are the aunt and father, which means that

3 are chosen, which means that

What is the probability that either your aunt or your father will become a city commissioner?

Probability of at least one of them being chosen, which is:

In which

Then

0.8 = 80% probability that either your aunt or your father will become a city commissioner.
