Roll the Dice:

Which number are you most likely to roll and why?

• It is equally likely to roll all of them because there is one of each number.

• You are more likely to roll a 6 because there are 6 numbers on the die.

• You are more likely to roll a 3 because there is a 50% chance and 3 is half of 6.

• It is more likely to roll a two because two is an even number.
