Sponsors of a local charity decided to attract wealthy patrons to its $500-a-plate dinner
by allowing each patron to buy a set of 20 tickets for the gaming tables.
The chance of winning a prize for each of the 20 plays is 50-50.
If you bought 20 tickets,
what is the chance of winning 15 or more prizes?
Please assist, I don't even know what kind of probability i'm looking for, let alone how to start.
