Amy and Miranda are arguing over who gets to use the car on Saturday night. Amy wants to go to see a play with her friends and Miranda wants to go to the mall with her friends.
Which of the following are fair methods for making a decision?

A) The girls have a scale that is accurate to the nearest hundredth of a gram. They put a sack of potatoes on the scale. If the hundredths digit is even, Miranda gets to use the car. If the hundredths digit is odd, Amy gets to use the car.

B) The girls decide to look up the 75th digit of pi - something neither of them has any knowledge of. If the 75th digit is even, Miranda gets the car. If it is odd, Amy gets the car.

C) Amy pulls out her graphing calculator. She commands the calculator to generate a random integer from
1 to 15 (inclusive). If the number is 7 or below, Amy gets the car. If the number is
9 or above, Miranda gets the car. If the number is 8, they generate a new number and repeat.

D) Amy throws two pennies into the air. If they are both heads, Amy gets the car. Otherwise, Miranda gets the car.
