1. Consider a 45-ball lottery game. In total there are 45 balls numbered 1 through to 45 inclusive. 4 balls are drawn (chosen randomly), one at a time, without replacement (so that a ball cannot be chosen more than once).

The winning number is announced on TV every night. If you purchased a ticket for $5 in Illinois and won, how much would you get if Illinois paid you according to your...

Let Xi = 1 if line i is a winner, and 0 otherwise, where i = 1, 2, 3, 4, 5 are the vertical lines and i = 6, 7, 8,...
