Dice Roll Probability

• What does a probability scale show?

  How likely something is to happen
• What does a probability of 0 mean?

  Something is impossible
• What is the range of a probability scale?

  From 0 to 1
• What does a probability of 1 mean?

  Something is certain
• What is a probability scale compared to?

  A number line
• How does the probability scale help visualize probabilities?

  It shows the range from impossible to certain
• What does a probability of 1 indicate?

  It will definitely happen
• How do you represent the probability of rolling a 6 on a probability scale?

  • Mark the point corresponding to $1 / 6$
  • Use a scale from 0 to 1
• How does the probability scale represent events that are uncertain?

  They are between 0 and 1
• What does it mean for a dice to be fair?

  Each side is equally likely to appear
• What probability are we trying to find when rolling a dice?

  The probability of rolling a 6
• How many sides does a dice have?

  6 sides
• What shape is a dice similar to?

  A cube
• What is the probability of rolling a 6 on a dice?

  1 in 6
• Why does each number on a fair die have the same probability of appearing?

  Because the die is fair with six sides
• How can you visualize the probability of getting a pizza slice on a number line?

  • The number line represents the pizza plate
  • Place a sticker (cross) where the slice is
• What are the key characteristics of a dice?

  • Has 6 sides
  • Shaped like a cube
  • Numbers range from 1 to 6
  • Only one number shows when rolled
• How likely is it to get that one slice?

  Not very likely, but not impossible
• What is the probability of getting one specific slice?

  $1 / 6$
• How do you mark the probability of $1 / 6$ on a scale from 0 to 1?


  1. Divide the scale into equal parts.
  2. Locate 0.17 between 0 and 1.
  3. Place a cross (x) at that point.
• If you roll a fair die, what is the chance of landing on any number?

  $1 / 6$
• What is the probability of rolling a 6 on a die?

  $1 / 6$
• Why is the probability of rolling a 6 considered a tiny bit away from 0?

  Because there is a chance of landing on 6
• What is the chance of rolling a specific side on a fair dice?

  $1 / 6$
• How does the number of sides on a die affect the probability of rolling a specific number?

  More sides decrease the probability for each number
• What does rolling a 6 on a dice indicate about its probability?

  It's more than never (0), but less than always (1)
• What does a probability of 0 indicate?

  It won't happen
• What is the approximate decimal value of $1 / 6$?


  About 0.17
• What does the number line represent in probability?

  It goes from 0 (never) to 1 (always)
• How is the question about rolling a 6 similar to asking about a favorite toy?

  Both involve uncertainty and chance
• Where should you mark the probability of rolling a 6 on the number line?

  Near the start, showing it's not very likely
• What happens when you roll a dice?

  Any number can show up, but only one
• What does putting an "X" on the road indicate about the event?

  It can happen, but it's not very likely
• What numbers are on a dice?

  Numbers from 1 to 6
• How is rolling a 6 on a dice represented in probability?

  Like getting one slice from a pizza cut into 6 pieces
• How many sides does a fair ordinary dice have?

  Six sides
