A class should carry out math activities in two places at the same time. Each student decides to go to one of the places by drawing lots, and draws three students, A, B and C, to go to the same place.

Firstly, draw a tree diagram according to the meaning of the question, then draw all possible results from the situation that the tree diagram and students A, B and C are drawn in the same place, and then use the probability formula to get the answer.

Solution: Draw a tree diagram:

∫ * * There are eight possible outcomes, and there are two situations in which students A, B and C are dragged to the same place.

The probability that students A, B and C are dragged to the same place is:

So the answer is:
