The expected value of buying one ticket in the fundraiser is calculated by multiplying the value of each prize by the probability of winning it and then summing the products. The expected value of a ticket is $5.5, which implies that an average gain or loss from buying a single ticket is $4.5 loss since each ticket cost $10.
The calculation of the expected value is straightforward and it involves multiplying the value of each possible outcome by its probability, and then adding these products together. So, let's start by identifying the outcomes:
Now we can calculate the expected amount you would get from buying 1 ticket:
(30000 * 1/8000) + (9000 * 1/8000) + (4000 * 1/8000) + (1000 * 1/8000) = $3.75 + $1.125 + $0.5 + $0.125 = $5.5
So the expected value of purchasing one ticket is $5.5. It's important to remember that this doesn't guarantee that you'll win because the actual result of buying one ticket is subject to chance.
