Question

using the letters from the word equation, how many 5-letter patterns can be formed in which q isfollowed immediately by u?

Answer 1

Using the arrangements formula, it is found that there are 720 words that can be formed.

The number of possible arrangements of n elements is the factorial of n, that is:

$A_n = n!$

In this problem:

• The non-qu letters of the word equation will be arranged in 5 positions.

• The "qu" can be positioned in 6 ways(letters 1-2 to letters 6-7), hence:

$T = 6 \times 5! = 6! = 720$

There are 720 words that can be formed.
