Total number of letters = 8

To find: possible number of three-letter words can be made using the letters of the word ‘ORIENTAL.’

Formula used:

Number of arrangements of n things taken r at a time = P(n, r)

Total number of arrangements

= P(8, 3)

= 8 × 7 × 6

= 336

Hence, the total number of three-letter words can be made by letters of the word ‘ORIENTAL’ = 336
