Questions & Step-by-Step Solutions
In a project with tasks P, Q, R, and S, if P must be completed before Q and R, and S can be done at any time, which of the following is a possible order of completion?
Step 1: Identify the tasks involved in the project: P, Q, R, and S.
Step 2: Understand the dependencies: P must be completed before Q and R.
Step 3: Note that S can be completed at any time, with no dependencies.
Step 4: Determine a possible order of completion that respects the dependencies.
Step 5: One valid order is to complete P first, then Q, then R, and finally S.
Step 6: Verify that this order follows the rules: P is done before Q and R, and S can be last.
