Question

In a game using a spinner with five equal parts numbered 1 to 5, a contestant wins when the spinner lands on an odd number. Is this game fair?

A. yes
B. no
C. not enough information

Answer 1

A. yes

Explanation:

The contestant has a 60% chance of winning because they could either spin 1, 3, or 5.

However, unless there's another player who can only spin evens, it's not fair, because the contestant who spins odds has a 60% chance, while this player will only have a 40% chance.
