We have 15 ways to chose 2 students for the position of president and Vice President
<em><u>Solution:</u></em>
Given that,
There are 6 students. 2 of them are chosen for the position of president and Vice President.
<em><u>To find: number of ways we have to choose the students from the 6 students</u></em>
So now we have 6 students, out of which we have to choose 2 students
As we just have to select the students. We can use combinations here.
In combinations, to pick "r" items from "n" items, there will be ways
<em><u>Then, here we have to pick 2 out of 6:</u></em>
Total students = n = 6
students to be selected = r = 2
Thus we have 15 ways to chose 2 students for the position of president and Vice President
