Activity A1 takes 5 weeks, A2 takes 7 weeks, and A3 takes 4 weeks with a 50% probability and 10 weeks with a 50% probability. What is the project completion time under the best-case scenario, that is, A3 is early and takes 4 weeks

12

Explanation:

The computation of the project completion time under the best-case scenario is shown below;

= Activity A1 weeks taken + activity A2 weeks taken

= 5 weeks + 7 weeks

= 12

We simply added the time taken by activity 1 and activity 2 so that the project completion time could come

answer; /// the above statement is (true);

the correct answer would be b, when, queen, calder hall and london.

explanation:

we always capitalize words when a paragraph or sentence is starting, when an important name is used, when a place is being written, or simply when a noun is used, etc. so in this sentence, sentence is starting from 'when', so it will be written in capital letters. secondly, queen is considered to be an important person, so it will also be written in capital letter. next, the name of the town is mentioned, i-e calder hall, which will also be written in capital letters. in the last,   city name is being used, 'london', which will also be written in capital letters. so option b is the most appropriate one.
