Illustrative Mathematics: S Md.2, 5 Sounds Really Good! (Sort Of)

Curated by ACT

A friend of yours, Phil, writes to you asking about a new scratch-off lottery game. It costs $10 to play this game. There are two outcomes for the game (win, lose) and the probability that a player wins a game is 60%. A win results in $15, for a net win of $5. Aligns with S-MD.A.2 and S-MD.B.5.
