Play a dice game of chance
Terry and Ali are playing a game with three balls. Is it fair that
Terry wins when the middle ball is red?
Erik can only choose dominoes which have an odd number of spots in total.
Sanjay chooses the dominoes which have an even number of spots.
Now they change the rules. They lay out the dominoes again.
Erik can only choose dominoes where the total number of dots is a multiple of $3$.
Sanjay chooses the dominoes where the total number of dots is not a multiple of $3$.
Who is able to pick up the most dominoes now? Is this fair? Explain your answer.
