Answer:
Negative Binomial
Step-by-step explanation:
The girl receives only 5% of mail which are addressed to her. Rest of 95% mails belong to other family members.
P (X) = 5%
P (X) = 95 / 5
P (X) = 19
The family receives 19 mails out of which only 5% will address the girl. The all other mails belong to the other family members.
Answer:

a=6 b=8 c=10
I'm so sorry if I got this wrong.

or
B-A=X
or
X=B-A

Amount paid for the first book is $17.
Amount paid for the second book is 0.75 x 8 = $6
Total amount paid = $17 + $6 = $23
Total full cost of the two books = $17 + $8 = $25
Amount of discount = $25 - $23 = $2
% reduction =

Therefore, the <span>percent of the total cost of the two books reduced during the sale</span> is 8%
