Dice Bingo Two dice are going to be rolled. The two scores will added and the square containing that value can be crossed out. Only one square can be crossed out each time. Draw a 3 x 3 grid and fill it with numbers that could appear. The winner will cross out all of their numbers first.
Dice Bingo Score 2 3 4 5 6 7 8 9 10 11 12 Tally Frequency What proportion of rolls resulted in a score of 5? This proportion is known as the relative frequency.
Dice Bingo A two way table is way to list all possible outcomes. Explain why we should have expected the mode to be 7.
Dice Bingo The probability of scoring a 7 is 6 36 7 8 6 7 8 8 The relative frequency of scoring a 7 from our bingo game was: 6 4 5 5 6 7 8 6 7 7 8 Discuss: Why are these proportions different?
Dice Bingo: Round 2 This time the product of the two scores will be used and the square containing that value can be crossed out. Only one square can be crossed out each time. Draw a 3 x 3 grid and fill it with numbers that could appear. The winner will cross out all of their numbers first.
