Robert and Makayla are on the student council at their high school. They both want to go to a dinner where student council representatives from other
schools will participate. However, only one student per school can go. How
can a fair decision be made about who goes to the dinner?
Select all that apply.
A. Ten cards have different numbers. Each student picks a card at
random. The student who picks the lower number wins.
B. Roll a number cube. If it lands on 1, 2, 3, or 4, Robert wins.
Otherwise, Makayla wins.
C. Give the students a math problem. The student who is first to
solve the problem wins.
D. Toss a coin twice. If both tosses are heads or both tosses are
tails, Makayla wins. If one is heads and one is tails, Robert wins.
