Given: the word is ‘MONDAY.’

To find: possible number of words using all the letters of the word ‘MONDAY.’

Total number of letters in the word= 6

Formula used:

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

Total number of arrangements

= the number of arrangements of 6 things taken all at a time

= P(6, 6)

{ 0! = 1}

= 6!

= 6 × 5 × 4 × 3 × 2 × 1
