The Wikipedia article on the length of dictionaries suggests there are 171,476 unique words in the English language. How many un
katrin2010 [14]

Answer:

806 million years

Step-by-step explanation:

From the information given:

Firstly, we need to determine the no. of ways we can choose n many words in the dictionary & array them in (^{171476}_{n}) * n! ways.

Thus, the no. of unique books possible of length till K is:

\sum \limits^k _{n=0} ( ^{171476}_{n}) * n! \\ \\ = \sum \limits ^k_{n=0} \dfrac{171476!}{(171476-n)!}

where K = 6, we have the value to be:

= 25420530373932821216635722990977

Thus, the time required to write all possible texts of 6 is:

=  (25420530373932821216635722990977)/10⁶

≅ 806 million years.
