Suppose you play a game with a biased coin. You play each game by tossing the coin once.  and . If you toss a head, you pay $10. If you toss a tail, you win $11. if you play this game many times, will you come out ahead? (i.e. will you gain extra money from playing this game?)  (Be sure to use fractions in the table.)

Dodgeball There is a dodgeball tournament with 8 teams. The committee has decided the best way to decide who the best team is to have each team play each other once. 1. How many games will there be? 2. If there were 10 teams, how many might there be? 3. How might you find out if there were 100? Or 222? (You do not have to solve. Just explain or show how you would find it.)

Please help me solve this practice question I found online

California Lotto officials want to try out a new "big wheel" game. This new game actually consists of two big wheels (spinners). The contestants spin Spinner 1, and then immediately after, they spin Spinner 2 to determine the "multiplier." When both spinners have stopped turning, the dollar amount shown on Spinner 1 is multiplied by the "multiplier" on Spinner 2 and the contestant wins that much money. $100800 20 50 150dp $1000 0.5 135° s5000 100 Spinner 1 Dollars Spinner 2 Multipliers What is the probability of winning the largest amount of money?
