Your school’s baseball team sells 1250 raffle tickets at $4 each. The grand prize is a $3000 boat. The second prize is a $450 gr

densk [106]

Answer:

The expected value of the winnings for a single-ticket purchase is -$1.0016.

Step-by-step explanation:

The total number of tickets sold is, N = 1250.

Cost of one ticket is, $4.

Let X = amount of prize.

The prize distribution is as follows:

1 Grand price = $3000

1 Second prize = $450

10 Third prize = $25

The expected value X can be computed using the formula:

$E(X)=\sum x.P(X)$

Compute the probability distribution of X as follows:

Prize Amount (X) P (X) x · P (X)

1 Grand prize $3000 $\frac{1}{1250}=0.0008$ $\$3000\times 0.0008=2.4$

1 Second prize $450 $\frac{1}{1249}=0.0008$ $\$450\times 0.0008=0.36$

10 Third prize $25 $\frac{10}{1248}=0.008$ $\$25\times 0.008=0.2$

No prize -$4 $1-\sum P(Win)\\=0.9904$ $-\$4\times 0.9904=-3.9616$

TOTAL 1.0000 -1.0016

Thus, the expected value of the winnings for a single-ticket purchase is -$1.0016.
