Multiple choice

A farmer is considering two different crop rotation systems, A and B. System A has a 10% chance of resulting in a yield loss of 20%, a 30% chance of resulting in a yield increase of 10%, and a 60% chance of resulting in no change in yield. System B has a 20% chance of resulting in a yield loss of 30%, a 40% chance of resulting in a yield increase of 20%, and a 40% chance of resulting in no change in yield. Which system has the lower risk of yield loss?

  1. System A

  2. System B

  3. Both systems have the same risk of yield loss

  4. Cannot be determined from the given information
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The risk of yield loss is measured by the expected value of the yield loss distribution. The expected yield loss for System A is (0.1 * -0.2) + (0.3 * 0.1) + (0.6 * 0) = -0.02. The expected yield loss for System B is (0.2 * -0.3) + (0.4 * 0.2) + (0.4 * 0) = -0.06. Therefore, System A has the lower risk of yield loss.
