Answer:
The probability is 2.2%
Step-by-step explanation:
The probability that a randomly selected adult uses the telephone in classes is always equal to 0.48.
If x represents the number of adults selected from among the 8 that the telephone uses in classes, then x is a discrete random variable that follows a binomial distribution, with:
p = 0.48
q = 0.52
n = 8
We want to find the probability of x = 5
The probability is 2.2%
1885.5 m^3 of water will fill the container.
To find how many cubic feet of water will it contain:
Given -
The pool comprises a 12-foot-radius cylinder with a height of 4.5 feet.
The volume of the water in this section of the cylinder will be equal to the volume of the cylinder formed.
Therefore, 1885.5 m^3 of water will fill the container.

The complete question is given below:
Lauren has an above-ground pool. To keep the pool's skimmer working well, the water level must be 4 inches from the top of the pool. When the pool is filled to this recommended level, approximately how many cubic feet of water will it contain? Use π = 3.14
A cylinder with a radius of 12 feet and a height of 4.5 feet.
