Answer 2

Answer:

The probability that there are exactly six letters between n & e is  $12.85$

Step-by-step explanation:

Word EQUATION has 8 letters

so total number of word can be formed are 8!

For exactly Six letters between N and E

N_ _ _ _ _ _E_ ,

And similarly other 5 will be formed by interchanging Q and S

so total favourable outcomes=1*6*6!

Probability =$\frac{1*6!*6!}{8!} =518400$

$\frac{518400}{40320} \\=12.85$
