I buy a $100 ticket from St. Judes. One winner gets a house valued at $490,000. They give away twelve other prizes all valued over $100 but I am unsure of the exact value. A total of 7,000 tickets will be sold so the chance of winning the house is 1/7000 (.01428571%), < 1/10th of 1%, but if I win the house I turn $1 into $4900. So, is this a +EV move to buy the ticket?
