Final answer:
To determine which stock will sell for a higher price on average, we need to calculate the expected values of the stocks. Stock 2 has a higher expected value, so it will sell for a higher price on average.
Step-by-step explanation:
To determine which stock will sell for a higher price on average, we need to calculate the expected values of the stocks.
For stock 1, we multiply the probabilities of selling for $10 or $20 by their respective prices and add them together. The expected value for stock 1 is (0.80 * 10) + (0.90 * 20) = 8 + 18 = 26.
For stock 2, we perform the same calculation. The expected value for stock 2 is (0.90 * 10) + (0.85 * 25) = 9 + 21.25 = 30.25.
Therefore, on average, stock 2 will sell for a higher price.
