In how many ways can you choose the head and the trade union leader of the group, if there are 25 people in the group?

1. Since there are only 25 people in the group, then when the choice of the headman will take place, there will be 25 different ways.

2. Further, when they choose a trade union organization, the choice will have to be made from the 24 remaining students. And whoever you would not choose the headman, for each candidate there are 24 candidates for the post of trade union organization. Therefore, let’s calculate how many different ways there are to choose the headman and the trade union organizer.

25 * 24 = 600 ways.

Answer: There are 600 ways to elect the headman and trade union organizer.
