-$1.43

Step-by-step explanation:

Total tickets = 3000

Cost per ticket = $2

Prize to be awarded = $1700

The chance of selling one ticket = 1/total tickets

The chance of selling one ticket = 1/3000

We are aslked to find the expected value of a single ticket


\begin{gathered} \text{Expected value = }price\text{ awarded }* Pr(selling\text{ one ticket) - cost per ticket (number of ticket in consideration)} \\ \text{number of ticket in consideration = single ticket} \end{gathered}
\begin{gathered} \text{Expected value = 1700(}(1)/(3000))\text{ - 2(1)} \\ \text{Expected value =0.5667 - 2 } \\ \text{Expected value = -1.4333} \\ \\ \text{Expected value of a single ticket in the raffle is -\$1}.43 \end{gathered}
