Megabucks is a lottery game played in Massachusetts with the following rules. A random drawing of 6 numbers out of all 36 numbers from 1 to 36 is made every Wednesday and every Saturday.
The game costs $1 to play, and to win a person must have the correct six numbers drawn, regardless of their order. (The numbers are sequentially drawn from a bin and are arranged from smallest to largest.
When a player buys a ticket prior to the drawing, the player must also arrange his or her chosen numbers in ascending order.) The jackpot depends on the number of players and is usually worth several million dollars. What is the probability of winning the jackpot?
