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) =

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.

27 + 13x + 15 = (x + 5)( =

step-by-step explanation:

27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( =
