Answer:
required probability is .3446
Step-by-step explanation:
It is given that most expected time of completion = 90 days
Variance = 25
We know that
Thus the standard normal deviate is given by
Applying values we get
Using the standard table for Z we have probability corresponding to Z = -0.4 equals 0.3446
Thus required probability is .3446
