Jaden · Answer 1

1000 (1/20000) +

300 (2/20000) +

10 (20/20000) +

=

1800/20000 =.09

Step-by-step explanation:

Each ticket purchased is expected to win 9 cents

Each ticket purchased cost 75 cents

If you interpret expected winnings per ticket to include the cost then each ticket is expected to lose 66 cents.
