Math problem: Three people perform a program. What changes can everyone's program make? Xiao Qiang sings, Xiaoming dances and Xiaohong performs sketches.

Are you talking about the change of program order? Or you can sing, dance and play skits to see how many different combinations there are?

If it is a sequence, there are six kinds of * * *, one of the three people ranks first, and the remaining two people have two kinds of sequences to change, so 3×2 = 6.

If the program changes in no particular order, there are six. Any one chooses a program, and the other two have two choices, so it is 3×2 = 6.
