For her Games Fair project, Lucia created a spinner with 15 sections with numbers 1 to 15 on each section. She charges each player $1 to play this game. The rule is simple. If a multiple of 3 (i.e. 3, 6 ...) is rolled the player wins $3. If a multiple of 7 is rolled the player wins $5. Is this a profitable game? To whom is it profitable? How do you know?
