Vedclass · Answer

(b) Total ways of arrangements $ = \frac{{8\,!}}{{2\,!\,\,.\,\,4\,!}}$

$ \bullet \,w \bullet x \bullet y \bullet z \bullet $

Now &lsquo;$S$&rsquo; can have places at dot&rsquo;s and in places of $w,\,\,x,\,\,y,\,\,z$

we have to put $2\,A's,$ one $I$ and one $N.$

Therefore favourable ways $ = 5{\rm{ }}\left( {\frac{{4\,!}}{{2\,!}}} \right)$

Hence required probability $ = \frac{{5\,.\,4\,!\,\,2\,!\,\,4\,!}}{{2\,!\,\,8\,!}} = \frac{1}{{14}}.$
