How much would it cost to get all the toys in a Happy Meal? The McDonald’s Happy Meal is a cultural phenomenon. Parents like it because it’s a quick and easy meal, and kids like it because it comes with a toy (typically part of a larger set).
Students use trials, probabilities, and expected value to determine how many meals it takes to get a complete set of Happy Meal toys and debate whether McDonald’s should allow customers to pay a fee to choose their own figurine.
