Question 44
A representative of the Environmental Protection Agency (EPA) wants to select samples from 10
landfills. The director has 15 landfills from which she can collect samples. How many different
samples are possible?
Solution
Since the arrangement does not follow a given order we apply combination.
nCr =
n!
r! (n − r)!
n = 15 and r = 10
nCr =
15!
15!
=
= 3,003
10! (15 − 10)! 10! × 5!
Answer: 3003
Question 46
A company is creating three new divisions and seven managers are eligible to be appointed head
of a division. How many different ways could the three new heads is appointed? Hint: Assume
the division assignment makes a difference.
Solution
Since the order of arrangement matters in this case, then we apply permutation
nPr =
n!
(n − r)!
n = 7 and r = 3
nPr =
7!
7!
= = 210
(7 − 3)! 4!
Answer: 210
