For this case, we can model the problem as a triangle with a right angle.
Where,
x, y: lengths of the sides of the triangle
d: hypotenuse of the triangle
We then have the following relationship:
Clearing d we have:

Answer: The probability that the project will be completed in 33 days or less is equal to<u> </u><u>0.73</u> .
Step-by-step explanation:
We assume that this is a normally distribution.
Given : The critical path length is 30 days .
i.e. Population mean =
Variance :
Then, standard deviation :
Z-score :
The value of z corresponding to 33 =
Now, the p-value =
Hence, the probability that the project will be completed in 33 days or less is equal to 0.73.
