Answer: False, there are actually 900 different three-digit numbers
========================================================
Explanation:
The three digit numbers span from 100 to 999, including both endpoints.
This means we have 999-100+1 = 900 different three-digit numbers.
You subtract the endpoints (large-small) and add 1 to include the lower endpoint.
Here's a smaller example of why this works: say you had the set {1,2,3,4} and we wanted to count the number of items in this set. Clearly there are 4 items. Note how subtracting the endpoints 4-1 gets us 3 instead, so we add on 1 to include that left endpoint.

1 3/4 because you have but how many times 4 goes into 7. Then use the difference as the numerator and use 4 as the bottom

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) =
