Question 36273: HI. Here is my problem:
Michico and Patricia are going to play a spinner game. These are the rules:
a) When it is a player's turn, she spins both spinners.
b) Then she adds the two numbers that the arrows point to.
c) If the sum is odd, Michico wins, even if it was not her turn.
d) If the sum is even, Patricia wins, even if it was not her turn.
Patricia tries a test spin first. Here is what she spins: The sum from the first spin is 3, because 3 + 0=3, Michico wins. Michico says, "I like this game. I have a better chance to win than you do." Patricia says, "No, I have a better chance to win than you do."
Use mathematics to decide which girl is right.
Thanks!

You can put this solution on YOUR website! IF (?) THERE ARE THE SAME NUMBER OF EVEN & ODD DIGITS/NUMBERS THEN THE ODDS ARE EVEN THE THE SUM IS ODD OR EVEN.
PROOF: ODD+ODD=EVEN ODD+EVEN=ODD EVEN+EVEN=EVEN & EVEN+ODD=ODD
