Answer:

Step-by-step explanation:
Given:
- p(x) = 2x2 - 1
- q(x) = 3(x - 1)
To find:
We know:
Substitute

<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) =
