Since we want ‘now’ in every word, we need to consider ‘now’ as one unit.
Thus, the word LUCKNOW will have only 5 different letters.
Now, we know the number of arrangements of 5 different letters is 5! = 120
The total number of arrangements = 7! = 5040
The probability of always having ‘now’ in the word = 120/5040 =1/42
