Answer:
0.726 is the probability that the project will be completed in 33 days or less.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 30 days
Variance = 25 days
Standard Deviation,

We assume that the distribution of path length is a bell shaped distribution that is a normal distribution.
Formula:

P(completed in 33 days or less)
Calculation the value from standard normal z table, we have,

0.726 is the probability that the project will be completed in 33 days or less.
