A charity raffle sells 2000 tickets for $1 each. Prizes are
awarded of one $100, four $50, and eight $25. Find the expected
value if you purchase 1 ticket. Your expected value should end up
negative since there are way more chances to not win than to win
one of the prizes. Expected value is calculated by multiplying
every possible outcome by its probability and then adding those
products. Let's break this down. a) In this case there are 2000...
