Simply subtract 8.72 from 20.08 and you get the answer which is 11.36$
Answer: 0.1824
Step-by-step explanation:
Given : The mileage per day is distributed normally with
Mean : 
Standard deviation : 
Let X be the random variable that represents the distance traveled by truck in one day .
Now, calculate the z-score :-

For x= 132 miles per day.

For x= 159 miles per day.

Now by using standard normal distribution table, the probability that a truck drives between 132 and 159 miles in a day will be :-

Hence, the probability that a truck drives between 132 and 159 miles in a day =0.1824
P=1886/25 or 75 11/25
Hope this helps :)
it is 56
because you need to break the figure into two parts
5 x 4 = 20
4 x 9 = 36
