Find the expected net gain to the player for one play of the game. If $x$ is the net gain to a player in a game of chance, then $E(x)$ is usually negative. This value gives the average amount per game the player can expect to lose. A charity organization is selling $\$ 5$ raffle tickets as part of a fund-raising program. The first prize is a trip to Mexico valued at $\$ 3450,$ and the second prize is a weekend spa package valued at $\$ 750 .$ The remaining 20 prizes are $\$ 25$ gas cards. The number of tickets sold is $6000 .$

Key Concepts

Probability

Probability measures the likelihood of a particular outcome occurring in a random event, expressed as a ratio or percentage of the number of favorable outcomes to the total number of possible outcomes. It is central to determining the contribution of each outcome to the overall expected value.

Outcome Analysis

Outcome analysis involves evaluating the various possible results of an event, including their associated net gains or losses and probabilities. This analysis helps in decision-making by illustrating the potential risks and rewards associated with participating in the activity.

Expected Value

Expected value is a fundamental concept in probability theory that calculates the average outcome of a random variable by summing the products of each possible outcome and their corresponding probabilities. It provides a measure of the long-term average result if an experiment or game were repeated many times.

Net Gain

Net gain refers to the actual profit or loss incurred after taking into account both the earnings and the expense of participating. In the context of games of chance or raffles, it is important to calculate net gain by subtracting the cost of playing from the value of any prize won.
