Respuesta :

Answer:

-$3

Explanation:

Data provided in the question:

Cost of raffle ticket = $5

Number of tickets sold = 2000

Probability of winning = 1 ÷ 2000 = 0.0005

Winning prize = $4,000

Now,

The expected value of prize =  Probability of winning × Winning prize

= 0.0005 × $4,000

= $2

Therefore,

The expected value for this raffle

= expected value prize - Cost of raffle ticket

= $2 - $5

= -$3
