Using the permutation formula, it is found that there can be 600 winning combinations.
There are roles involved(president, vice-president, secretary and treasures), hence the order is important and the <em>permutation formula</em> is used.
<h3>What is the permutation formula?</h3>
The number of possible permutations of x elements from a set of n elements is given by:

In this problem:
- For president and vice-president, 2 students are chosen from a set of 6.
- For secretary and treasurer, 2 students are chosen from a set of 5.
Hence:

There can be 600 winning combinations.

Scholarships and merit aid are the best way to earn money to go to college. They don't have to be paid back. When it comes to loans, you should select federal before non-governmental because the interest rates are usually lower on federal loans.
One of the most fundamental truths of (Euclidean) geometry is that the ratio of the circumference to the diameter of any circle is a constant, and that constant is called pi (denoted by π π). Let C be the (length of the) circumference of a circle, and let d be its diameter. Then, we must have: C d = π C d = π
Yes that is correctttttttttttttttt
