If everyone mixes their hats and receives one at random, will anyone receive their own?
A class drops distinct hats into one shared basket and receives one hat per child without looking, creating a familiar ownership puzzle with an exact one-to-one rule.
Talk about it
- What must stay true when the hats mix so this remains a one-to-one handout?
- Why can one fair sample contain several matches while another contains only one?
- What would we need to count if we wanted evidence stronger than three examples?
