At a Christmas bazaar, 6000 lottery tickets were sold at a price of $5 each. There are 15 prizes to be won from the lottery: a car with a value of $15 000, three trips to exotic locations, each of which costs $2500, a TV set whose value is $700 and 10 mobile phones each of which costs $250. Helena bought a ticket for this lottery.

What is her expected “net profit” from the lottery draw?
