Answer:
Step-by-step explanation:
Given that the number of drivers who travel between a particular origin and destination during a designated time period has a Poisson distribution with parameter μ = 20 (suggested in the article "Dynamic Ride Sharing: Theory and Practice"†).
a) 
b) 
c) 
d) 2 std dev = 2(20) =40
Hence 2 std deviation means
20-40, 20+40
i.e. (0,60)

Step-by-step explanation:
Area of building is
.
<u>Step-by-step explanation:</u>
Here we have , a figure in given below picture where we have to find volume of this office building , Let's find out:
If we look closely we see that it's basically cuboid with dimensions 50 m by 110 m by 70 m . But there's one small cuboid sliced off from this cuboid with dimensions 50 m by 10 m by (110-90) m i.e. 50 m by 10 m by 20 m .
Area of building = Area of larger cuboid - Area of smaller cuboid
Area of cuboid = 
⇒ Area of building = Area of larger cuboid - Area of smaller cuboid
⇒ 
⇒ 
⇒ 
Therefore, Area of building is
.
