Answer:
Explanation:
Grand prize = $15,000
Second prize = $1,500
Number of tickets sold = 12,000
The probability of getting the grand prize ($15,000) is 1/12,000
The probability of getting the second prize ($1,500) is 1/12,000
Each ticket costs $4
Expected value is -4 + 1/12,000 X 15,000 + 1/12,000 X 1,500
= -1.5.
The expected winnings for a ticket buyer is therefore -$1.5
