Suppose that there are 10 dimes, 15 nickels and 8 quarters in a bag and one coin is drawn from the bag. what is the expected value of the draw in dollars? (round to the nearest cent.)

Total the dollar value of all the coins:

10 dimes = 10 * 0.10 = $1.00

15 nickels = 15 * 0.05 = $0.75

8 quarters = 8 * 0.25 = $2.00

total value: 2.00 + 1.00 + 0.75 = $3.75

total coins: 10 + 15 + 8 = 33

expected value = total value / total coins:

3.75 / 33 = $0.11
