Bruce is going to call one person from his contacts at random. He has 25 total contacts. 20 of those contacts are from his neighborhood. What is P(call a person not from his neighborhood)

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) =

it's

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
