I don't understand what they're getting at.
working out the premise, assuming these probabilities are uniform over 10 uses of the tool:
1 a. reduces time by 2 * 10 = 20 hours
1 b. reduces time by 5 * 5 + 5 * 0 = 25 hours
2 b. reduces time by 4 * 7 + (-1 * 3) = 25 hours
3 b. reduces time by 6 * 9 + (-4 * 1) = 50 hours
