Let’s Roll Some Dice

Today, we are going to be looking at a different type of probability. Instead of tossing a coin, we will be rolling some dice. There will be some writing off the board which will be important so make sure you write down the notes fully and carefully.

ALL OF THESE ANSWERS SHOULD BE WRITTEN IN YOUR BOOK

PART 1 – Rolling Dice

Q1) Show the different options you can get when you roll a die (that’s one dice).

Q2) What probability (that’s fraction, decimal or percentage) is there to roll each of the 6 different options.

Q3) HERE is a link to a die roller. Choose ‘d6′ and roll the die 10 times. Record the results using the method shown to you earlier in the lesson.

Q4) Which was the most common number rolled? Is this what we expected?

Q5) How could we improve the accuracy here? Explain.

PART 2 – Rolling Dice

Q1) When you roll 2 dice, how many different options are there? Write down these options.

Q2) When we add the numbers together there are 11 possible options (between 2-12). Find out the probability of rolling 2 dice and the total adds up to 2, 3, 4, 5 ….. 12.

Q3) Which number between 2-12 are we most likely to roll in we roll 2 dice? Explain

Q4) Which numbers between 2-12 are be most unlikely (most uncommon) to roll if we roll 2 dice? Explain. Show the probability as a percentage, decimal or fraction.

Q5) Using this link HERE , roll 2 dice 20 times and add up the amounts. Keep the results in a table such as that shown earlier in the lesson.

Q6) Which numbers ended up being the most common? Explain.

Q7) How could we improve the accuracy of the our results so they looked more like the probability seem in Q4.
