Q. How many ways can 5 different letters be arranged such that two specific letters are never together?
A.
48
B.
60
C.
72
D.
96
Solution
Total arrangements = 5! = 120. Arrangements with the two letters together = 4! * 2! = 48. So, arrangements where they are not together = 120 - 48 = 72.
Q. How many ways can 5 different letters be arranged such that two specific letters are always together?
A.
48
B.
60
C.
120
D.
24
Solution
Treat the two specific letters as one unit. Then, we have 4 units to arrange: 4! = 24. The two letters can be arranged in 2! = 2 ways. Total = 24 * 2 = 48.
