Math Problem Statement
In the UK, a ticket for the national lottery costs $2.
All prizes are paid as a lump sum and are tax-free. Of all money spent on National Lottery tickets, 53% goes to the prize fund; 25% to "good causes"; 12% to the UK Government as lottery duty; 5% to retailers as commission; 5% to operator Camelot.
Given only this information, we cannot compute the expected value of purchasing a ticket for an individual lottery, singe such a calculation depends on the number of tickets purchased and whether prize money has "rolled over" from previous lotteries.
However, what is the expected value of the act of purchasing a ticket at random for an arbitrary national lottery?
(You may answer either in terms of dollars or cents).
