Answer:
110 combinations.
Step-by-step explanation:
We are going to be choosing without replacement.
Out of 11 people, we can choose one president, but after choosing, we would be left out with 10 people to choose a vice president from.
To calculate the possible combinations of president and vice-president, we multiply 11 by 10
11 x 10
= 110
Therefore we have 110 vice-president/president possible combinations.
