Question

How many ways are ther eto line up the 12 people if the bride must be next to the maid of honor?

Answer 1

the number of ways to line up the 12 people if the bride must be next to the maid of honor is 132 ways.

How to determine the permutation

The formula for finding the number of arrangement is given as;

Permutation = $\frac{n!}{n - r!}$

Where;

• n is the total number of object
• r is the number of selected objects

From the question given, we can deduce that

n = 12 people

r = 2, because they must come next to each other and is taken as 2

We then have,

Permutation = $\frac{12!}{12 - 2!}$

Permutation = $\frac{12!}{10!}$

Permutation = 132 ways

This is to tell us that the number of ways to arrange the people is 132 ways

Thus, the number of ways to line up the 12 people if the bride must be next to the maid of honor is 132 ways.
