Calculate the expected Gain of Loss of stock ABC.<br> Please help if you can!
andreyandreev [35.5K]
<h3>Answer: $11 gain</h3>

==================================================

Explanation:

Focus on the first row only. We won't worry about the other stocks.

Convert each of the percentages to decimal form

  • 40% = 0.40
  • 15% = 0.15
  • 45% = 0.45

Then multiply those decimal values with their respective gains or losses.

Use a negative sign to indicate losses.

  • 0.40*(-25) = -10
  • 0.15*5 = 0.75
  • 0.45*45 = 20.25

The last step is to add up each of the results to get the expected value.

-10+0.75+20.25 = 11

The result is positive, so it's a gain rather than a loss.

On average, we expect an $11 gain for stock ABC.

----------

Side note: Thank you for making the screenshot much more clear.
