Bruce is going to call one person from his contacts at random. He has 25 total contacts. 20 of those contacts are from his neigh

Naya [18.7K]

<h3>P(call a person not from his neighborhood) = $(\frac{1}{5} )$ </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) = $\frac{\textrm{Total Favorable Outcomes}}{\textrm{Total Outcomes}} = \frac{20}{25} = (\frac{4}{5})$

So, the probability of calling a person from his neighborhood is $(\frac{4}{5} )$

⇒P(E) = $(\frac{4}{5} )$

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

$= 1 - (\frac{4}{5}) = \frac{5-4}{5} = (\frac{1}{5})$

⇒P( not E) = $(\frac{1}{5} )$

Hence, P(call a person not from his neighborhood) = $(\frac{1}{5} )$

mihalych1998 [28]

Answer:

D) $46800

===========================

The amount of simple interest is:

Interest = Loan * rate * time

I = P * r * t

Given:

P = $60000, r = 6.5%, t = 12 years

Substitute and calculate:

I = 60000*(6.5/100)*12 = 46800

The matching choice is D.

Two-thirds of a number minus six is 2

Vlada [557]

(2/3)n - 6 = 2

Add 6 to both sides.
(2/3)n = 8

Divide by 2/3.
n = 9 / (2/3)
n = 27/2, or 13.5
