Suppose we want to choose letters, without replacement, from distinct letters.

Juli2301 [7.4K]

The number of ways when the choice is not relevant is 1716

<h3>How to determine the number of ways?</h3>

The number of letters are:

Letter, n = 13

The letter to choose are:

r = 6

<u>Relevant choice</u>

When the choice is relevant, we have:

$Ways = ^nP_r$

This gives

$Ways = ^{13}P_6$

Evaluate

Ways = 241235520

Hence, the number of ways when the choice is relevant is 1235520

<u>Not relevant choice</u>

When the choice is not relevant, we have:

$Ways = ^nC_r$

This gives

$Ways = ^{13}C_6$

Evaluate

Ways = 1716

Hence, the number of ways when the choice is not relevant is 1716
