The Robot Dance Crew

Problem illustration

At a huge festival, a team of 24 amazing robots performed a jaw-dropping martial arts dance. These weren't slow, clunky robots—they were super agile! They performed perfectly synchronized backflips, jumped over 3 metres into the air, and even did breakdancing spins. Before they ever performed live, the robots practiced in a computer simulation hundreds of millions of times to make sure every single move was perfect. Learn more!

Wee Ones

A robot's first command is: 1. Wake up. Its second command is: 2. Bow. When the robot starts, which command does it follow first?

Little Kids

A group of 24 robots needs to be split into 3 equal dance troupes. If you share them equally, how many robots are in each troupe?

Big Kids

A team of 7 robots performs a jump. Scientists measure how many full rotations each one does. The results are: 2, 3, 3, 4, 3, 1, 3. What is the most common number of rotations (the mode) in this set of data?

The Sky's the Limit

After millions of practice runs, a robot succeeds at a backflip 99 out of every 100 attempts. What is the theoretical probability, as a percentage, that the robot will *fail* on its next attempt?
