- In a bag, a child has 325 coins worth $19.50. There were three types of coins: pennies, nickels, and dimes. If the bag contained the same number of nickels as dimes, how many of each type of coin was in the bag?If a man has 4 sweaters and 5 pairs of slacks, how many different outfit can he wear?A bag contains 2 gold marbles, 8 silver marbles, and 26 black marbles. Someone offers to play this game: You randomly select one marble from the bag. If it is gold, you win $4. If it is silver, you win $3. If it is black, you lose $1.
- In this game, two chips are placed in a cup. One chip has two red sides and one chip has a red and a blue side. The player shakes the cup and dumps out the chips. The player wins if both chips land red side up and loses if one chip lands red side up and one chip lands blue side up. The cost to play is $4 and the prize is worth $6.

The club is selling Chinese fortune cookies at a price of $3 per cookie. Each cookie contains a piece of paper with a different number written on it. A random drawing will determine which number is the winner of a dinner for two at a local Chinese restaurant. The dinner is valued at $39. Since fortune cookies are donated to the club, we can ignore the cost of the cookies. The club sold 720 cookies before the drawing. Lisa bought 32 cookies. What is the probability she will not win the dinner for two? Write your answer as a fraction in the simplest form, if one exists.

Why or why not?A man went to Atlantic City with $2000 and placed 100 bets of $20 each, one after another, on the same number on the roulette wheel. There are 38 numbers on the wheel, and the gaming casino pays 35 times the amount bet if the ball drops into the bettor’s numbered slot in the roulette wheel. In addition, the bettor receives back the original $20 bet. Estimate how much money the man is expected to win or lose in Atlantic City.
