Answer:

<h2>3/5</h2>

Step-by-step explanation:

If Jennifer has 25 books on her bookshelf and she has 10 fiction books, the number of non-fiction books she has will be 25-10 = 15 non- fiction books.

Probability is the likelihood or chance that an event will occur.

Probability = Expected outcome of event/total outcome.

Since we want the expression that represents the probability that the book she selects will be a non-fiction book, our expected outcome will be 15(the total non fiction she selected)

The total outcome will be the total number of books i.e 25.

Probability that she elects non fiction book = 15/25

= 3/5

1/8 inch thick
inner diameter of 8.5

volume shell=volume total-volume shell


1/8=0.125

diameter/2=radius
radius inner=8.5/2=4.25
radiustotal=inner+outer=4.25+0.125=4.375


so

Vouter-Vinner=(4/3)pi4.375³-(4/3)pi4.25³
Vshell=(4/3)(pi)(4.375³-4.25)

Sergio [31]
<span>It's 1/r! 

nCr = n! / r!(n-r)! 
nPr = n! / (n-r)! 

If you divide the two you'd have: 

n! / r! (n-r)! * (n-r)! / n! = 1/r!

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!
