Question 22 options:
The quality of a device should be examined in the inspection department sequentially in three steps before it is sent to packaging department. The probability distributions for the time required to complete each of the activities are given in the table above.
When answering the following question, just enter the number -- no dollar signs or other text is necessary.
Considering that shorter times are better, compute total time the three steps for the worst case scenario.
Considering that shorter times are better, compute total time the three steps for the best case scenario.

Worst case:
11 * 0.25 + 13 * 0.30 + 15 * 0.45 = 13.4
Best case:
3* 0.15 + 5 * 0.25 + 7 * 0.35 + 9 * 0.25 = 6.4
Base case:
8 * 0.35 + 10 * 0.20 + 12 * 0.45 = 10.2
