Question

In the new movie, Kung Fu Panda, Po the Panda trains to become a martial-arts master! He practices with his idols, the Furious Five. Po and the other five kung fu fighters each practice with one another one time, how many practices will they have?

Answer 1

There will be a total of 20 training sessions.

Easy to figure using 1,2, 3, 4, 5 instead of the names

1 will practice with 2,3,4,5

2 will practice with 1,3,4,5

3 will practice with 1,2,4,5

4 will practice with 1,2,3,5

5 will practice with 1,2,3,4

Since each one does not practice with themselves that means that they can only practice four times each.

Each will practice with the other four only once so 5 time 4 equals 20.
