Answer: a) 0.8413, b) 0.9987.
Step-by-step explanation:
Since we have given that
Mean = 3 pounds
Standard deviation = 0.25 pounds
n = 28 bricks
So, (a) What is the probability that all the bricks in the sample exceed 2.75 pounds?

b) What is the probability that the heaviest brick in the sample exceeds 3.75 pounds?

Hence, a) 0.8413, b) 0.9987.
A:
Width of the deck =
units
Length of the deck =
units
So area of rectangular deck = Length * width
= 
Area = 
Area=
units square
As mentioned in part B, the area of the pool is
so the combined area of the deck and pool is
Area = area of rectangular deck + area of pool
=
unit square
B:
The area of only the deck is
unit square
