The prize in a raffle is a flat-screen TV valued at $350, and 1,000 tickets are sold for a dollar each. Let's find the expected value if you buy 1 ticket. Find the expected value. Round your answer to two decimal places. Remember a gain would be posit

the expected value EV = - $0.65

Step-by-step explanation:

Expected value EV = expected gain - expected loss

Given;

Cost of a ticket L = $1

Probability of losing the ticket P (L) = 999/1000 = 0.999

Cost of a flat screen TV = $350

Expected gain G = $350 - $1 = $349

Probability of winning the TV P (G) = 1/1000 = 0.001

EV = G * P (G) - L * P (L)

Substituting the values;

EV = $349 * 0.001 - $1 * 0.999

EV = - $0.65

the expected value EV = - $0.65
