• Autum and Lani

• Madison and Regina

• Kaleigh and Bridget

Which type of 'roll' seems match the 'expected (theoretical) outcome best in 6th Period?

• Rolling Two evens

• Rolling Doubles

• Rolling Snake Eyes

• Rolling Both Even or Both odd

• Rolling a sum > 6.

Consider the data of Autumn and Lani (6th Period). Which of their 'types of rolls' seem to most closely match the expected outcome? Simply look at the difference between the theoretical and actual value.

• Two Evens

• Doubles

• Both Even / Both Odd

• Sum > 6
