Letters in "COURTESY": C, O, U, R, T, E, S, Y
The word must start with C and end with Y.
Formula used:
\(P = 6!\) , where 6! represents the arrangement of the remaining 6 letters between C and Y.
Calculations:
The first and last letters are fixed as C and Y, leaving 6 letters (O, U, R, T, E, S) to be arranged.
⇒ \(P = 6!\)
⇒ 6! = 6 × 5 × 4 × 3 × 2 × 1 = 720
∴ The correct answer is 720.
