Final answer:
The subject of this question is Mathematics, specifically probability and expected value. Expected value is a concept in probability that represents the average outcome of a random event over a long number of trials. In this case, the expected value of the carnival game is -$0.62, indicating an average loss per game.
Step-by-step explanation:
The subject of this question is Mathematics, specifically probability and expected value.
Expected value is a concept in probability that represents the average outcome of a random event over a long number of trials. It is calculated by multiplying each possible outcome by its probability and summing them up.
In this case, the carnival game charges each contestant $2 to spin a wheel with 555 equally likely spaces. The expected value of the game is -$0.62, which means that on average, a player would lose 62 cents per game.
