The video tutorial introduces the game of Subtractor Bingo, explaining how to set up the game and calculate probabilities. Students learn to convert fractions to percentages for easier comparison and explore the differences between experimental and theoretical probabilities. The tutorial concludes with designing a 'perfect card' based on probability predictions, highlighting discrepancies between expected and actual outcomes.

What is the main purpose of the diagram in the subtractor bingo game?

• To show the arrangement of numbers and dice

• To list the players' names

• To calculate the total score

• To display the rules of the game

How do you determine the probability of getting a specific score in subtractor bingo?

• By guessing based on previous games

• By asking the teacher

• By calculating the number of favorable outcomes over total outcomes

• By rolling the dice multiple times

Why are percentages used instead of fractions in the probability table?

• Fractions are too complex to calculate

• Percentages are more accurate

• Fractions are not allowed in the game

• Percentages are easier to compare

What is a potential issue with rounding percentages in probability calculations?

• They might not add up to 100%

• They become too large

• They are difficult to understand

• They require a calculator

What was the total number of dice rolls conducted in the experimental probability exercise?

• 52

• 100

• 36

• 12

Why might the experimental results differ from the theoretical probabilities?

• Random variation in dice rolls

• Theoretical probabilities are always incorrect

• The dice were biased

• The game rules were changed

What is the purpose of designing a 'perfect card' in subtractor bingo?

• To confuse the players

• To make the game more challenging

• To match the theoretical probabilities as closely as possible

• To ensure a win every time

How many zeros should be on the 'perfect card' based on theoretical probabilities?

• Three

• One

• Two

• Four

What percentage of the 'perfect card' should be filled with the number one?

• 17%

• 28%

• 11%

• 22%

Why might a 'perfect card' not always win in subtractor bingo?

• The game is rigged

• Theoretical probabilities do not guarantee outcomes

• The card is not actually perfect

• The players cheat
