In this activity, students randomly choose nine answers from a grid and place them in a 3x3 square. They then answer questions about the relative frequency of events in a game of Bingo, such as the spinner landing on a certain number or the dice landing on a certain number. The activity aims to assess if the spinner and dice are biased. Printing instructions are provided.
