A) \[\frac{1}{6}\]
B) \[\frac{5}{6}\]
C) \[\frac{1}{3}\]
D) \[\frac{2}{3}\]
Correct Answer: A
Solution :
Number of ways in which 6 letters of the word 'PENCIL' can be arranged is P(6,6)=6! If N is next to E, they can be considered as one and the 5 letters can be arranged in P(5, 5) = 5 ! ways \[\therefore \] Required probability \[=\frac{5!}{6!}=\frac{1}{6}\]You need to login to perform this action.
