Question

When activity times are uncertain:______.
a. assume they are normally distributed.
b. calculate the expected time, using (a 4m b)/6.
c. use the most likely time.
d. calculate the expected time, using (a m b)/3.

Answer 1

Answer:

b. calculate the expected time, using (a 4m b)/6.

Step-by-step explanation:

In project management, when activity times are uncertain, the appropriate approach is to calculate the expected time using the following expression:

$T =\frac{a+4m+b}{6}$

Where 'a' is the most optimistic outcome, 'm' is the most likely time, and 'b' is the most pessimistic outcome.

Therefore, the answer is b. calculate the expected time, using (a 4m b)/6.
