A) Interest = principal * rate * time
I = (800)(0.05)(3) = $120
b) $800 + $120 = $920 after the three years. $920 * (1 - 0.02) = $901.60.

Answer with explanation:</h2>
Given : The critical path for the project has an expected duration of 112 days, and a standard deviation of 5 days.
i.e. 
We assume that this a normal distribution.
Let x be the random variable that represents the time duration to complete the project.
z-score : 
For x= 115

P-value : 
Thus, the probability of finishing on time if the due date is 115 days is 0.726.
Also, for x= 120

P-value : 

Hence, the probability that they will have to pay the penalty is 0.055 .
