The simulation of the customer visit is an illustration of probability
The probability that a customer would visit the coffee shop at least 5 times to win a gift card is
<h3>How to design the simulation?</h3>
From the question, we understand that every 12th customer gets a $5 gift card.
This means that the probability that a customer gets a gift card is:
p = 1/12
The probability that a customer would visit the coffee shop at least 5 times to win a gift card is calculated using the following complement rule:
P(x ≥ 5) = 1 - P(x <5)
The equation becomes
P(x ≥ 5) = 1 - P(0) - P(1) - P(2) - P(3) - P(4)
Using the binomial formula
The equation becomes
Simplify
Hence, the estimate that a customer would visit at least 5 times is

Im pretty sure this is right.
I could barely see the picture
The volume of the sphere depends on its radius. The volume of the sphere is 623.3 ft3.
Option D shows the correct value of the volume of the sphere.
<h3>
What is the volume of a sphere?</h3>
The volume of a sphere is defined as the space occupied by a sphere in 3-dimensions.
Given that the radius of the sphere is 5.3 ft. The formula to calculate the volume of a sphere is,
Where r is the radius of the sphere.
Hence we can conclude that the volume of the sphere is 623.3 ft^3.

Answer:
x=21
Step-by-step explanation:
x/x+14=9/15
15x=9x+126
6x=126
x=21
