Number of ways in which the 3 can be selected from 13 = 286
Step-by-step explanation:
Step 1:
Number of books considered by the textbook search committee = 13
Number of books selected from this 13 = 3
We need to determine number of ways in which the 3 can be selected from the 13
Step 2 :
The order of the 3 books selected does not matter. So,
Number of ways in which the 3 books can be selected from 13 books = C(13,3) = 
=
=
= 286
Step 3 :
Answer :
Number of ways in which the 3 can be selected from 13 = 286
This is the answer
if u do 3rd, 4th .... derivatives the answer will be 0 again.
(14 over 5) · (15 over 5)
= 14·13·12·11·10/5! · 15·14·13·12·11/5!
= 6012006
(n over k) is the Binomial coefficient
Provided his $100 budget is for millage only
100/22= $4.54 per day for miles
4.54/0.27= 16.835 miles per day
It would be $7.50 because 4 ounces equals $1 so 30/4 =7.5
