Answer:

Step-by-step explanation:

Total no of word that can be formed from the letters of the word 'ARTICLE'=7!=7*6*5*4*3*2*1

Total no of word having vowels at even places=3!*4!

So, probability=Word having vowels at even places / Total no of words

=(3!*4!)/(7!)

=(3*2*1*4*3*2*1) / (7*6*5*4*3*2*1)

=1 / 35

So, Option (B) is correct
