<h3>
P(call a person not from his neighborhood) = 
</h3>
Step-by-step explanation:
Here, the total number of contacts in the list if Bruce = 25 contacts
The total number of neighbors in the contact = 20 people
Now, let E: Event of calling a person from his neighborhood
So, P(E) = 
So, the probability of calling a person from his neighborhood is 
⇒P(E) =
Now,as we know: P(E) + P(not E) = 1
So, the probability of NOT calling a person from neighborhood
= 1 - probability of calling a person from his neighborhood

⇒P( not E) = 
Hence, P(call a person not from his neighborhood) = 
Answer: 7 bags of popcorn
Step-by-step explanation: In this problem, we know that Katie sold 35 bags of popcorn and she sold 5 times as many as Aaron.
We can find out how many bags of popcorn Aaron sold by dividing the number of bag of popcorn that Katie sold by 5.
35 ÷ 5 = 7
This means that Aaron sold 7 bags of popcorn for the fundraiser.
The volume of the air space surrounding the cone inside the cylinder is 1055.04 cm³
<h3 />
<h3>How to find volume?</h3>
The volume of the air space surrounding the cone inside the cylinder is as follows:
volume of the air space = volume of cylinder - volume of a cone
volume of cylinder = πr²h
volume of cylinder = π16 × 5²
volume of cylinder = 400π
volume of the cone = 1 / 3 πr²h
volume of the cone = 1 / 3 × π × 12 × 4²
volume of the cone = 64π
Therefore,
volume of the air space = 400π - 64π
volume of the air space = 336π
volume of the air space = 1055.04 cm³
